The invention proposes the integration and the processing of n virtual smart cards in a support card with n chips (N = 2) with a community identification code. In this case N = A 2, the main chip (chip No. 1) makes it possible to process the information of conventional routines (card authentication, identification of the cardholder) of electronic cards, the second (chip No. 2) manages community reference applications (virtual cards and community services linked to these cards). The first receives the information from the outside contact (TPEC or TPE, DABC or DAB) elaborates it and transmits it to the external servers in case of acceptance of continuation of the processing of the request, it challenges the second chip for the continuation processing, the second activated chip processes the instructions with respect to the preliminary data in memories of the chip n ° 2. Chips # 1 and # 2 are all structured microcontroller, ROM, RAM, eeprom memories, serial input / output interface, Vcc, Rst, Clk, Gnd and processes necessary for their operation . The main chip (1) communicates with the outside for the exchange of request execution information and with the second chip for the preliminary information in memory (management of n smart cards) by the input / output line bidirectional I / O. The Community identification code is the first security key that activates the ability of the external contact to read the No. 1 chip.
