    Hi!

    Help me pls to understand : How to get a list of card numbers, if some MIFARE cards (for ex. 4 or 5) are placed near MFRC522 antenna ? is it possible , or MFRC522 can communicate only with one card ?

    The MFRC522 provides the functionality to operate ISO/IEC 14443 type A cards or tags. This ISO standard describes how to activate a single card, even with more than one card in the field. This is called anticollision procedure. This procedure can be used to activate and de-activate cards.
    So in principle the operation of more than one tag/card is possible.
    Details can be found in the literature and in the library code.
