The role of payment gateways and save merchants the cost of interfacing with banks!

A payment gateway is the interface between a bank's network system and the Internet network. It is a set of server devices operated by banks to convert data transmitted over the Internet into internal data of financial institutions.

The APP payment gateway is a set of server devices operated by banks to convert the data transmitted on the Internet into the internal data of financial institutions, or a designated third party to process merchant payment information and customer payment instructions.

The function of payment instructions is mainly to decrypt the communication protocols sent from the Internet, repackage the data according to the communication protocol standards of the bank's private network, and then send the data to the bank's private network.

In this case, the bank's host does not need to be modified. Then, the bank-specific communication protocol is repackaged according to the Internet protocol standards, the data is encrypted and transmitted over the Internet.

The payment institutions connected to the different online banks are in fact the "front office" of an integrated bank providing online banking services.

The seller only needs to connect to one payment institution's interface, and the user can pay the seller using the Internet banking of several banks that cooperate with the payment institution.

This saves the seller the trouble of developing data interfaces with multiple commercial banks and saves the seller's cost.
