    Mainstream contactless smart card IC

    Originality function
    The originality function is implemented by an AES authentication with the originality key.
    The authentication is performed in ISO/IEC 14443-4 protocol layer.
    8.2 Card activation and communication protocol
    The ISO/IEC 14443-3 anticollision mechanism allows for simultaneous handling of
    multiple PICCs in the field. The anticollision algorithm selects each PICC individually and
    ensures that execution of a transaction with a selected PICC is performed correctly
    without data corruption from other PICCs in the field.
    There are three different versions of the PICC. The UID is programmed into a locked part
    of the NV-memory reserved for the manufacturer:
    unique 7-byte serial number
    unique 4-byte serial number
    non-unique 4-byte serial number
    Due to security and system requirements, these bytes are write-protected after being
    programmed by the PICC manufacturer at production.
    Remark:
    The programmed 4-byte NUID serial number is not globally unique which has to
    be considered in the contactless system design. See
    Ref. 11
    for further information
    regarding handling of UIDs.
    The customer must decide which UID length to use when ordering the product, see
    Table 2
    for ordering information.
    During personalization, the PICC can be configured to support Random ID in security
    level 3. The user can configure whether Random ID or fixed UID shall be used. According
    to ISO/IEC 14443-3 the first anticollision loop (see
    Ref. 5
    ) returns the Random Number
    Tag 08h, the 3-byte Random Number and the BCC, if Random ID is used. The retrieval of
    the UID in this case can be done using the Virtual Card Support Last command, see
    Ref. 3
    or by reading out block 0.
    8.2.1
    Backwards compatibility protocol
    The backwards compatibility of this product, as used in security level 1 and security
    level 2, runs on the same protocol layer as MIFARE Classic 1K and MIFARE Classic 4K.
    The protocol is formed out of the following components:
    Frame definition: according to ISO/IEC 14443-3
    Bit encoding: according to ISO/IEC 14443-2
    Error code handling: handling is proprietary as error codes are formatted in half bytes.
    Command specification: commands are proprietary. Please use the specification as in
    Ref. 1
    and
    Ref. 2
    and the additional commands which are only implemented in
    MIFARE Plus as described in this document and in
    Ref. 3
    .
    The following security levels can run on this protocol:
    Security Level 0
    Security Level 1
