Contact or contactless communication object e.g. contact or contactless credit card, reading device for contactless terminal, has microcontroller to control device for assuring contactless communication between terminal and contact object

摘要

The device (1) has a communication interface (19b) cooperated with a communication interface of a contact communication object. A clock (18) synchronizes actions of the device. A microcontroller (15) e.g. ATmega169P type microcontroller, controls the device for displaying information or parameter of a transaction between a contactless terminal and a contactless communication object on a display screen (11) i.e. LCD, or for realizing contact communication between the device and the contact object and assuring contactless communication between the terminal and the contact object. An independent claim is also included for a contactless communication object comprising a signal processing unit.
