摘要

The method involves communicating data between a pay transaction card (1) and a terminal device (2). The device uses the data to determine whether an application program is executable within the pay transaction card. The device transmits information about its functionalities to the card if the application program is executable within the card. The information is then displayed on a display (5). An independent claim is also included for a system for executing a transaction via a pay transaction card and a terminal device.
