Overview

The point of sale (POS) access service is a smart card service widely used in places such as shopping malls and gasoline service stations. It enables a POS terminal located in a shopping mall or a gas station to access a bank card accounting system to provide services.

Early POS terminals from different banks could not communicate with each other. A technology based on a shared POS access service solves this problem by allowing bank cards from different banks to be used on the same POS terminal.
