Technical Examples

The invention relates to cards with a microprocessor and contacts. The invention lies in the fact that a communication device of the asynchronous type is disposed between the contacts and the microprocessor so as to relieve the microprocessor of the communication tasks and thus allow better use of the central unit of the microprocessor and the associated memories. This device includes an analysis circuit, a circuit for checking the integrity of the series of pulses, a circuit for determining the characters in the series of pulses and pluralities of registers which are connected with the microprocessor.
