POS Access Service Point of Sale (POS) service is a type of smart card service widely used in shopping

Overviewmalls, gas stations, and so on. It links the POS terminal device at the commercial client (located in shopping mall or gas station) to the bank card accounting system to provide service.

The POS terminal device is widely used in the fields of commerce, finance, taxation, and so on. The earlier POS terminal devices worked independently in different banks, and they could not communicate with each other. The technology based on a shared POS access service has solved this problem and makes it possible to use different bank cards on the same POS.

The POS terminal is connected to the transaction center in two ways, namely, through dial-up POS access and POS network access.

Dial-up POS Access

In the dial-up POS access mode, after responding to the smart card, the POS terminal device will synchronously or asynchronously dial up with the built-in modem. Thus the POS terminal device at the commercial client accesses the bank card accounting system. In this case, the 3Com Router series providing POS access service can be placed at the commercial client side. The routers can be connected to the front end processor via the WAN. They can also be connected to the front end processor of the bank via the asynchronous interface or Ethernet port.

The following figure shows the networking diagram of the typical dial-up POS access.
