METHOD, SYSTEM, AND NON-TRANSITORY COMPUTER READABLE RECORD MEDIUM FOR PAYMENT LINK

1 . A payment link method implemented by a computer system, the payment link method comprising:

verifying whether a second payment application is a transaction link target in response to a transaction request, which is received from a first payment application installed on an electronic device, occurring at a payment processing system that uses the second payment application different from the first payment application; and

forwarding payment information on the first payment application to a payment server associated with the second payment application and linking a transaction between the first payment application and the second payment application in response to the second payment application corresponding to the transaction link target.

2 . The payment link method of claim 1 , wherein the linking the transaction comprises processing the payment information on the first payment application to information transactable on the second payment application and forwarding the processed payment information to the payment server.

3 . The payment link method of claim 1 , wherein the linking the transaction comprises:

verifying that an amount corresponding to the transaction request from a user account of the first payment application is deposited; and

settling the deposited amount to be transferred to the payment server based on a preset condition.

4 . The payment link method of claim 1 , wherein the linking the transaction comprises creating a virtual user of the second payment application for an authorized user of the first payment application.

5 . The payment link method of claim 1 , wherein the verifying comprises retrieving the second payment application from a list of payment applications pre-registered as targets to support a heterogenous payment link between different payment applications.

6 . The payment link method of claim 1 , wherein the payment server associated with the second payment application is a second payment server, and

wherein the linking the transaction comprises processing a payment for product transaction information created by the second payment application through interaction with a first payment server associated with the first payment application and the second payment server in response to receiving a payment request from the first payment application for the product transaction information.

7 . The payment link method of claim 1 , wherein the payment server associated with the second payment application is a second payment server, and

wherein the linking the transaction comprises processing a remittance for an amount corresponding to a remittance request through interaction with a first payment server associated with the first payment application and the second payment server in response to receiving, from the first payment application, the remittance request for the payment processing system that uses the second payment application.

8 . The payment link method of claim 1 , further comprising:

selecting a payment application to be used for a first transaction with the first payment application based on priority set by the computer system or the payment processing system in response to a plurality of payment applications comprising the second payment application being used at the payment processing system.

9 . The payment link method of claim 1 , further comprising:

selecting a payment application to be used for a second transaction with the second payment application based on priority set by the computer system or the payment processing system, in response to a plurality of payment applications comprising the first payment application being used by the electronic device.

10 . The payment link method of claim 1 , wherein the linking the transaction comprises linking the transaction between the first payment application and the second payment application based on exchange rate information between a first currency used in the first payment application and a second currency used in the second payment application in response to the first currency being different from the second currency.

11 . A non-transitory computer-readable record medium storing instructions that, when executed by a processor, cause the processor to perform the payment link method of claim 1 .

12 . A computer system comprising:

at least one memory configured to store computer-readable instructions; and

at least one processor configured to execute the computer-readable instructions to:

verify whether a second payment application is a transaction link target in response to a transaction request, which is received from a first payment application installed on an electronic device, occurring at a payment processing system that uses the second payment application different from the first payment application; and

forward payment information on the first payment application to a payment server associated with the second payment application and link a transaction between the first payment application and the second payment application in response to the second payment application corresponding to the transaction link target.

13 . The computer system of claim 12 , wherein the at least one processor is further configured to execute the computer-readable instructions to:

process the payment information on the first payment application to information transactable on the second payment application; and

forward the processed payment information to the payment server to link the transaction between the first payment application and the second payment application.

14 . The computer system of claim 12 , wherein the at least one processor is further configured to execute the computer-readable instructions to:

verify that an amount corresponding to the transaction request from a user account of the first payment application is deposited; and

settle the deposited amount to be transferred to the payment server based on a preset condition.

15 . The computer system of claim 12 , wherein the at least one processor is further configured to execute the computer-readable instructions to:

create a virtual user of the second payment application for an authorized user of the first payment application.

16 . The computer system of claim 12 , wherein the at least one processor is further configured to execute the computer-readable instructions to:

retrieve the second payment application from a list of payment applications pre-registered as targets to support a heterogenous payment link between different payment applications.

17 . The computer system of claim 12 , wherein the payment server associated with the second payment application is a second payment server, and

wherein the at least one processor is further configured to execute the computer-readable instructions to:

process a payment for product transaction information created by the second payment application through interaction with a first payment server associated with the first payment application and the second payment server in response to receiving a payment request from the first payment application for the product transaction information.

18 . The computer system of claim 12 , wherein the payment server associated with the second payment application is a second payment server, and

wherein the at least one processor is further configured to execute the computer-readable instructions to:

process a remittance for an amount corresponding to a remittance request through interaction with a first payment server associated with the first payment application and the second payment server in response to receiving, from the first payment application, the remittance request for the payment processing system that uses the second payment application.

19 . The computer system of claim 12 , wherein the at least one processor is further configured to execute the computer-readable instructions to:

select a payment application to be used for a first transaction with the first payment application based on priority set by the computer system or the payment processing system, in response to a plurality of payment applications comprising the second payment application being used at the payment processing system.

20 . The computer system of claim 12 , wherein the at least one processor is further configured to execute the computer-readable instructions to:

link the transaction between the first payment application and the second payment application based on exchange rate information between a first currency used in the first payment application and a second currency used in the second payment application in response to the first currency being different from the second currency.
