ABSTRACT:
The present invention relates to an apparatus for exchanging information between integrated circuit identification cards, also called smart cards, and a terminal device. The circuit solution disclosed herein allows the solution of the problem of interfacing between microprocessor and smart card, in full compliance with international standard IS07816-3, through the use of low cost components. It uses a bidirectional buffer circuit and a control device so as to control information exchange between the smart card and a terminal device so that the microprocessor handles fast events and the card handles other events.
