Contactless integrated circuit containing a hardwired anticollision circuit

The integrated circuit (CIC) has a comparator (SCOMP) which receives an incoming (RFI) selection code (MV) from a shift register (SREG) and register loading means (CNTR). The comparator also receives the integrated circuit identification (ID) from a series memory (SMEM) and if the two are compatible...

Zusammenfassung:	The integrated circuit (CIC) has a comparator (SCOMP) which receives an incoming (RFI) selection code (MV) from a shift register (SREG) and register loading means (CNTR). The comparator also receives the integrated circuit identification (ID) from a series memory (SMEM) and if the two are compatible data in the shift register after shifting (CNTR) are sent to a communication interface (ADC,RFI) at a determined time Independent claims are also included for the following: Smartcard or portable electronic label equipped to execute selective identification request. Method for executing in integrated circuit a selective identification request accompanied by a selection code
