NETWORK TRANSACTION PAYMENT METHOD AND SYSTEM
Technical Field
[0001] The present invention relates to the field of computer technology,
and particularly to a
network transaction payment method and system.
Background Technology
[0002] With the development of the Internet, communication between people
and the network is
becoming closer and closer, and e-commerce has gradually become the main trend
of Internet
economic development. On-line consumption has gradually become a way of life
because merchants
and users fail to achieve face-to-face payment settlement. The most critical
part of e-commerce is to
reduce the transaction risk of buyers and sellers. At present, the traditional
network payment adopts
the form of a third-party payment company guarantee in which the buyer (the
payer) will pay the
funds to the third party platform, which will transfer the funds to the
account of the seller (receiving
side). However, if the form of third-party payment company guarantee is
applied to the payer (the
buyer) before the goods are received, the funds will have already been paid to
the third party payment
company. Therefore, once the third-party payment company encounters
difficulties, the payment side
of the funds may fail to be guaranteed. In this situation, the receiving side
(the seller) will have
shipped the goods but the payment for goods will fail to be guaranteed, and so
the traditional network
payment method leads to a high incidence of network transaction risk of funds.
Summary of the invention
[0003] Based on the foregoing, it is necessary to provide a kind of network
transaction payment
method and system that can reduce the risk of network transactions due to the
above technical
problems.
[0004] A kind of network transaction payment method includes:
[0005] The first terminal transmits the credit certificate and the purchase
information data packet
to the second terminal;
[0006] The second terminal parses the purchase information data packet to
obtain the payment
amount and determines whether the payment amount is less than or equal to the
issuance amount
corresponding to the said credit certificate, and if so, sends the receiving
request including the
payment amount and the credit certificate to the second server;
[0007] The second server sends a payment request containing the credit
certificate and the
payment amount to the first server;

certificate sent by the
second terminal, the second server also includes:
[0015] The second terminal receives the logistics information corresponding
to the merchandise
returned by the logistics server and generates the corresponding paying
certificate according to the
logistics information.
[0016] In one of the examples, before the first terminal transmits the
credit certificate and the
purchased information data packet to the second terminal, the method further
includes:
[0017] The first terminal sends the issuing request to the first server,
the issuing request includes
the payment account number and the issuing amount;
[0018] The first server will freeze the funds of the issuing amount
corresponding to the said
payment account number; if the freezing is succeeded, the credit certificate
corresponding to the
issuing amount will be generated, and the said credit certificate shall be
returned to the first terminal;
if the freezing is failed, the issuing failure information will be generated,
and the said issuing failure
information shall be returned to the first terminal.
[0019] In one of the examples, after the second server sends a payment
request containing the
credit certificate and the payment amount to the first server, the second
server also includes:
[0020] The first server verifies whether the credit certificate is
consistent with the credit
certificate returned to the first terminal and, if so, updates the amount of
the issuance of the credit
certificate to the amount obtained by the amount of the issuing amount minus
the payment amount.

is successful, according to the credit certificate, the payment of funds for
the goods corresponding to
the payment account shall be de-blocked;
[0028] The first server transfers the said funds to the pre-set receiving
account through the second
server.
[0029] In one of the examples, after the first server receives the steps of
the payment request
including the paying certificate and the credit certificate sent by the second
server, the first server
also includes:
[0030] The first server verifies whether the credit certificate corresponds
to the credit certificate
returned to the first terminal, and if so, the credit certificate
corresponding issuing amount will be
updated to the amount of the issuing amount minus payment amount.
[0031] In one of the examples, after the first server updates the issuing
amount corresponding to
the credit certificate to the amount obtained by using the issuing amount
minus the payment amount,
the first server further includes:

transaction payment system in
one example.
Description of the Preferred Examples
[0051] The present invention will be described in further detail with
reference to the
accompanying drawings and the accompanying examples, so as to describe the
invention purposes,
technical solutions and advantages more clearly. It is to be understood that
the specific examples
described herein are merely illustrative of the invention and are not intended
to limit the invention.
[0052] One of the innovations of the examples of the present invention is
that, in conjunction
with the freeze payment of the silver letter of credit, a new payment model is
implemented, through
which the buyer can verify the seller's transaction progress, and by this
setting, the buyer's financial
security at the same time to urge the seller to actively deliver, set the
conditions in the various stages
of payment, reduce the funds to recover the process to solve the technical
problem hereinabove
identified, from the system level to ensure that buyers and sellers enjoy
integrity of the transaction.
[0053] As shown in Figure 1, in one example, there is provided a network
transaction payment
method comprising the steps of:
[0054] In Step 102, the first terminal transmits the credit certificate and
the purchase information
data packet to the second terminal.
Date Recue/Date Received 2021-11-12
[0055] The first terminal is suitable for the payment party in the payment
of the network
transaction. The second terminal is suitable for the seller in the network
transaction. In one example,
the buyers and sellers complete the network transaction through the online
shopping platform. The
credit certificate is a kind of electronic certificate for handling payment
and settlement that the buyer
uses the corresponding funds of his payment account to guarantee the payment
for goods.
Specifically, the credit certificate corresponds to a string of specific
serial numbers, which act as
unique identifiers of the credit certificate. The payment account includes a
bank account number or
the third party's payment account.
[0056] The first terminal generates a shopping order based on the
merchandise shopping
information submitted by the user and calculates the amount of payment
required for the purchase of
the order item, and further generates the purchase information data packet
according to the purchase
order and the payment amount. The first terminal sends the purchase
information data packet together
with the credit certificate to the second terminal to realize the buyer's
request to purchase the
merchandise from the seller.
[0057] In one example, the network transaction payment method also
includes: the first terminal
sends an issuing request to the first server before the first terminal
transmits the credit certificate and
the purchase information data packet to the second terminal in Step 102. The
issuing request includes
payment account and issuing amount; the first server freeze the funds of the
issuing amount
corresponding to the payment account; if the freezing is succeeded, the
issuing amount corresponded
credit certificate will be generated; the credit certificate will be returned
to the first terminal; if the
freezing is failed, the issuing certificate failure information will be
generated, and the issuing
certificate failure information will be returned to the first terminal.
[0058] The buyer in advance before the network transaction out of the
credit certificate, through
the advance payment account corresponding to the funds to show the seller that
the buyer has the
ability to pay the purchase price. In the present example, the first server is
provided with a payment
account by the buyer to pay the payment, and the buyer can freeze the payment
account corresponding
to the payment through the first server and automatically transfer to the
payment account of the seller
the payment to be paid.
[0059] The amount of credit is the credit limit of the credit certificate,
for example, the amount
of 5,000 RMB, out of the credit certificate can be used as a purchase of 5,000
RMB of goods credit
guarantee. The funds of the credit certificate corresponding to the issuing
amount are not diverted
before they are unfrozen. To ensure that the seller to recover the security of
the purchase price.
[0060] In one example, the first terminal establishes a connection with the
first server over the
network. The issuing request also contains the user name and user password of
the payment account.
The first server verifies whether the buyer has permission to open the credit
by checking the user
6
Date Recue/Date Received 2021-11-12
name and the user password. In one example, the reason for the failure of the
issuance request includes
that the amount corresponding to the payment account is less than the amount
of the issuing or the
legitimacy verification of the first server to the issuing request, etc. If
the first server will not be able
to generate the credit certificate, it will issue a failure message to the
first terminal to remind the
buyer.
[0061] In Step 103, the second terminal parses the purchase information
data packet to obtain the
payment amount and determines whether the payment amount is less than or equal
to the amount of
the issuance corresponding to the credit certificate. If so, the process
proceeds to Step 104.
[0062] In the present example, the second terminal, after receiving the
shopping data packet,
further judges whether the buyer has sufficient funds to pay for the purchased
goods. In the present
example, it is determined whether or not the payment amount is equal to or
less than the amount of
the issuance corresponding to the credit certificate; if so, the buyer's
frozen funds are sufficient to pay
the purchase of the merchandise network transaction, and the process proceeds
to Step 104. If not,
then the buyer to freeze the lack of funds to pay for the purchase of goods,
the network transaction
has failed, and the buyer can choose to buy other goods or exit the shopping
platform.
[0063] In Step 104, the second terminal transmits a payment request
including the payment
amount and the credit certificate to the second server.
[0064] The second server is connected with the second terminal through the
network, the second
server is provided with the receiving account of the buyer, and the second
server is used to transfer
the payment of the purchased goods paid by the buyer into the receiving
account, and in one example,
the second server is pre-set with the account number. After the seller
receives the buyer's shopping
request, the second terminal further sends a payment request to the second
server, and the second
server requests payment from the first server to the first server.
[0065] In Step 105, the second server sends a payment request containing
the credit certificate
and the payment amount to the first server.
[0066] In the present example, when the second server receives the
receiving request sent by the
second terminal, the second server transmits the payment request to the first
server according to the
receiving request, that is, to notify that the first server credit certificate
corresponding to the issuing
amount shall be used for payment for goods in on-line transactions. During the
course of a network
transaction, the funds for the corresponding amount of credit will not be
diverted.
[0067] In one example, on the right of Step 105, the method also includes:
the first server verifies
whether the credit certificate is consistent with the credit certificate
returned to the first terminal and,
if so, updates the issuing amount corresponding to the credit certificate to
the amount of the issuing
amount minus the payment amount.
7
Date Recue/Date Received 2021-11-12
[0068] The first server judges whether the credit document sent by the
second server is generated
by itself, and if so, the credit certificate is legally valid. As the credit
card corresponding to the amount
of the amount of funds has been partially or will be entirely used to pay the
payment, and further
credit card corresponding to the amount of funds to make the appropriate
adjustments, by issuing the
amount minus the amount of payment to update the corresponding credit
certificate by the amount of
the buyer to facilitate the next shopping, to avoid buyers disposing of all
the money after the purchase
of the credit certificate.
[0069] In one example, after the first server updates the issuing amount
corresponding to the
credit certificate to the amount of the issuing amount minus the payment
amount, the method further
includes:
[0070] If the first server fails to receive the paying certificate sent by
the second server within the
pre-set time range, the issuance amount of the updated credit certificate is
restored to the amount of
the issuance before the update.
[0071] In the present example, the network transaction process is limited
to the pre-set time range,
that is, the time from the order of the buyer to the seller to the buyer's
receipt is set within the pre-set
time range. If the first server does not receive the receipt document sent by
the second server within
the pre-set time range, the default network transaction has been suspended for
some reason. For
example, the unqualified buyer refused to sign or the buyer and the seller
reached an agreement to
cancel the network transaction, and still other reasons. As the buyer has no
obligation to pay the
purchase price, in order not to affect the buyer's next shopping, the credit
certificate corresponding to
the amount of the amount of recovery is restored to the amount before the
update.
[0072] In Step 106, the second server receives the paying certificate sent
by the first terminal, the
paying certificate including the corresponding payment, and sends the paying
certificate to the first
server.
[0073] In the actual network transaction process, the buyer to receive the
goods and the seller to
send the goods may be different, resulting in the amount of payment payable
being different to the
actual amount of payment. For example, the buyer in the seller's shop would
buy five cups, but the
buyer fails to sign for 2 of the cups, and so the paying certificates
corresponding to the money should
be for three cups instead of for 5 cups. The second terminal generates the
paying certificate based on
the information of the network transaction which the buyer and the seller has
completed, and sends
the paying certificate to the second server, and the second server requests
the first server to pay the
payment.
[0074] In one example, at Step 106, before the second server receives the
paying certificate sent
by the second terminal, the method also includes: the first terminal transmits
the confirmed receipt
8
Date Recue/Date Received 2021-11-12
information of the signed goods to the second terminal; the second terminal
generates the
corresponding paying certificate as per the confirmed receipt information.
[0075] In the present example, the buyer may voluntarily send to the seller
a receipt information
confirming that the goods have been checked, and the buyer, by clicking on the
merchandise by the
first terminal on the shopping platform, confirms the goods receipt, further
triggering the first terminal
and transmitting the confirmation receipt information to the second terminal.
The second terminal
generates the paying certificate based on the confirmation receipt
information.
[0076] In another example, at Step 106, the second server receives the
paying certificate sent by
the second terminal, the method further including:
[0077] The second terminal receives the logistics information corresponding
to the merchandise
returned by the logistics server and generates the corresponding paying
certificate according to the
logistics information.
[0078] In the present example, when the buyer sends the issuing request
through the first terminal,
the payment is set by the credit document, and the payment is made in
accordance with the logistics
information of the merchandise. The merchandise's logistics information will
be recorded in the
logistics server, for example, when the goods are received by the consignee,
the logistics company's
staff will submit information that the goods have been signed into the
logistics server, which has
signed the information, including the recipient's signature and sign time and
other information.
[0079] The logistics server realizes the logistics information of the goods
to the second terminal
in real time, and the logistics information obtained by the second terminal
conforms to the pre-set
condition, that is, the corresponding paying certificate is generated
according to the logistics
information. For example, the logistics server records the logistics
information that the seller
completed the delivery task, the generated paying certificate requires the
buyer to pay part of the
purchase price, when the logistics server records the logistics information
that the buyer has signed
the goods, the buyer needs to make the remaining payment by the generated
paying certificates
[0080] The first server according to the logistics information of the goods
in batches pays the
credit corresponding to the funds. The goods will be divided into multiple
stages of payment. The
seller can be encouraged to actively fulfil the obligations of the
implementation of the contract to
ensure that the buyer's funds at the same time urge the seller to complete
active delivery, to achieve
the integrity of buyers and sellers transactions.
[0081] In one example, the logistics server sends the logistics number
corresponding to the goods
after shipment to the first terminal and the second terminal to facilitate the
transaction tracking of the
buyers and sellers to the purchased goods.
9
Date Recue/Date Received 2021-11-12
[0082] In Step 107, the first server verifies the legitimacy of the paying
certificate, after the
verification is successful, according to the credit certificate, the funds for
payment of the goods
corresponding to the payment account shall be de-blocked.
[0083] In Step 108, the first server transfers the funds to the pre-set
receiving account through the
second server.
[0084] In the present example, the first server pays the debit amount
corresponding to the
payment account to the pre-set collection account through the second server,
thereby realizing the
payment obligation of the buyer to purchase the goods. Completed the network
transaction.
[0085] In one example, data packets are modified in order to prevent data
leakage or encounter
hacking. Data such as purchase information data packets, paying certificates
and credit certificates
are encrypted during the transmission process, that is, the above data packets
contain the encryption
section. Specifically, the above data contains the encryption section using
the MAC algorithm for
encryption.
[0086] In the above-mentioned network transaction payment method, the first
terminal
corresponding to the buyer has already obtained the credit certificate before
purchasing the goods.
The credit certificate provides a guarantee for the buyer to make payment for
the goods, ensures
seller's security, and makes the seller comfortable to make delivery. The
funds of the payment account
will not be paid before the first terminal corresponding to the buyer has
completed the transaction.
Accordingly, the security of the buyer may advantageously be guaranteed. The
above method of
network transaction payment is achieved without relying on a third-party
payment platform and
improves the funds security of on-line transactions. At the same time, the
payment for goods within
the payment account of the buyer does not have to be made in advance. In case
the seller does not
complete the delivery, the payment for goods can gain interest in the
corresponding the payment
account, which increases the funds and the funds security of the buyer.
[0087] As shown in Figure 2, in an embodiment, the buyer A issues an
issuing request for a 5,000
RMB credit certificate to the first server 22 through the first terminal 21,
and the first server 22 will
freeze the deposit amount of 5,000 RMB in the payment account and will
generate the credit
certificate with a value of 5,000 and return same to the first terminal 21. On
the shopping platform,
the buyer A goes into the seller B's e-shop to buy goods, but the purchased
goods must be less than
or equal to 5,000 RMB so as to achieve the transaction. The payment for goods
purchased by the
buyer A is guaranteed by the 5,000 RMB credit guarantee. After the buyer and
the seller have reached
a deal agreement, the seller B arranges for the logistics company to send the
goods. The logistics
company records the logistics information of the merchandise into the
logistics server 25, the logistics
server 25 returns the logistics information to the second terminal 23, the
second terminal 23 generates
the corresponding paying certificate, and the second terminal 23 transmits the
paying certificate to
Date Recue/Date Received 2021-11-12
the second server 24, the second server 24 sends a paying certificate and a
credit certificate request
payment for goods to the first server 22, the first server 22 de-blocks the
funds in the payment account
according to the credit certificate, and transfers the funds to the receiving
account of the seller B
through the second server 24 so as to complete the network transaction
payment.
[0088] In one example, as shown in Figure 3, there is provided a network
transaction payment
method that applies the first server; the method includes the steps as below:
[0089] In Step 302, the first server receives an instruction from the first
terminal to send the
issuing request, and the issuing request includes the payment account number
and the issuing amount.
[0090] In Step 304, the first server freezes the funds corresponding to the
issuing amount of the
payment account number, and if the freezing is successful, the credit
certificate corresponding to the
issuing amount is generated and the credit certificate is sent to the first
terminal. If the freezing fails,
the issuing failure message generates, and the issuing failure message is sent
to the first terminal.
[0091] In Step 306, the first server receives the payment request including
the paying certificate
and the credit document sent by the second server, and the paying certificate
includes the
corresponding payment for goods.
[0092] In Step 308, the first server verifies the legitimacy of the paying
certificate, and after the
verification is successful, according to the credit certificate, the funds for
payment of the goods
corresponding to the payment account are de-blocked.
[0093] In Step 310, the first server transfers the funds to the pre-set
receiving account through the
second server.
[0094] In one example, at Step 310, the first server passes the funds
through the second server to
the pre-set payment account, the method further including: the first server
generates a message that
the payment was successful and sends the message that the payment was
successful to the first
terminal.
[0095] As shown in Figure 4, in one example, in Step 306, the first server
receives the payment
request including the paying certificate and the credit certificate sent by
the second server, further
including:
[0096] In Step 402, the first server verifies whether the credit
certificate corresponds to the credit
certificate sent to the first terminal. If so, then go to Step 404, if not,
then the end.
[0097] In Step 404, the amount of the card issuance corresponding to the
credit is updated to the
amount obtained by the amount of the debit amount minus the payment amount.
[0098] In one example, in Step 404, after the first server updates the
issuing amount
corresponding to the credit certificate to the amount obtained by the issuing
amount minus the
payment amount, the method further includes:
11
Date Recue/Date Received 2021-11-12
[0099] In Step 406, when the first server does not receive the paying
certificate sent by the second
server within the pre-set time range, the issuance amount corresponding to the
updated credit
certificate is restored to the amount of the transaction before the update.
[0100] As shown in Figure 5, there is provided a network transaction
payment system including:
a first terminal, a second terminal, a first server, and a second server,
wherein the first terminal 11 is
connected to the first server 12; the terminal 13 is connected to the second
server 14, the first terminal
11 is connected to the second terminal 13, and the first server 12 is
connected to the second server
14. The first teaninal 12 is connected to the second server 14.
[0101] The first terminal 11 is used for transmitting a credit certificate
and a purchase information
data packet to the second terminal 13.
[0102] The second terminal 13 is used for parsing the payment amount of the
purchase
information data packet and determining whether or not the payment amount is
equal to or less than
the issuance amount corresponding to the credit certificate, and if so,
sending the payment request
including the payment amount and the credit certificate to the second server
14.
[0103] The second server 14 is used for sending a payment request including
a credit certificate
and a payment amount to the first server 12, the paying certificate is sent by
the second terminal 13,
and the paying certificate includes a corresponding payment for goods; in
accordance with the
payment request, the paying certificate and the credit certificate are sent to
the first server 12.
[0104] The first server 12 verifies the legitimacy of the paying
certificate, and after the
verification is successful, the payment for goods corresponding to the payment
account is de-blocked
according to the credit certificate, and the funds are transferred to the pre-
set receiving account
through the second server 14.
[0105] In one example, the first terminal 11 is also used to send the
confirmed receipt information
to which the goods have been signed to the second terminal 13.
[0106] The second terminal 13 is also used to generate the corresponding
paying certificate based
on the confirmation receipt information.
[0107] In one example, the second terminal 13 is also used to receive the
logistics information
corresponding to the merchandise sent by the logistics server and generate the
corresponding paying
certificate based on the logistics information.
[0108] In one example, the first server 12 is also used to generate a
message that the payment was
successful and to send a message that the payment was successful to the first
terminal 11.
[0109] In one example, the second server 14 is also used to generate a
message that the payment
was successful and send a message that the payment was successful to the
second terminal 13.
[0110] In one example, the first terminal 11 is also used to send the
issuing request to the first
server 12, which includes the payment account and the issuing amount.

[0111] In one example, the first server 12 is also used to freeze the funds
of the payment account
corresponding to the issuing amount, and if the freeze is successful, the
credit certificate
corresponding to the issuing amount is generated and the credit certificate is
sent to the first terminal
11. If the freeze fails, then an issuing failure message is generated and sent
to the first terminal 11.
[0112] In one example, the first server 12 is also used to verify that the
credit certificates are
consistent with the credit certificate sent to the first terminal 11 and, if
so, update the issuing amount
corresponding to the credit certificate to the issuing amount minus the
payment amount after the
amount obtained.
[0113] In one example, the first server 12 is further configured to restore
the payment amount
corresponding to the updated credit certificate to the pre-update issuing
amount if the paying
certificate sent by the second server 14 is not received within the pre-set
time range.
