7.5.10 ISO14443-4 type A commands
MF_Restore
Copy one or several value blocks on a MIFARE card. If more than one block is copied, the
SAM accesses the blocks in the same order as addresses listed in the command data
field. The order of the status code is the same as the order of addresses in the data field.
If copying of a block fails, the SAM returns the 4-bit status code of the MIFARE card in the
lower nibble and the hexadecimal value ‘F’ in the higher nibble of the status byte SW2. No
information about the block write error is provided. Be aware that some blocks may have
been updated already.
MF_AuthenticateRead
Performs an authentication with subsequent reading of blocks on a MIFARE card. The
command allows authenticating and reading several different blocks on the card within
one command. Several blocks can be read without re-authenticating, but also several
blocks with different authentications. For each block address needing a new
authentication, the key to authenticate with and whether it shall be diversified has to be
specified. If a key is used for accessing different blocks but a new authentication is
necessary, these blocks have to be listed consecutively in the data field and the re-use to
be indicated by a flag. If more than one block is read, the SAM accesses the blocks in the
same order as addresses listed in the command data field. The order of the returned data
is the same as the order of addresses in the data field.
MF_AuthenticateWrite
Performs an authentication with subsequent writing of blocks on a MIFARE card. The
command allows authenticating and writing several different blocks on the card within one
command. Several blocks can be written without re-authenticating, but also several blocks
with different authentications. For each block address needing a new authentication, the
key to authenticate with and whether it shall be diversified has to be specified. If a key is
used for accessing different blocks, these blocks have to be listed consecutively in the
data field and the re-use to be indicated by a flag. If more than one block is written, the
SAM accesses the blocks in the same order as addresses listed in the command data
field.
MF_ChangeKey
This command is intended to change a key in a MIFARE card. The command offers the
possibility to prepare and write an encrypted data stream to a MIFARE 1K or 4K card
containing the desired keys and the given access conditions. The first case requires an
active MIFARE authentication for producing the stream to be sent to the card.
ISO14443-4_RATS_PPS
Execute a combined RATS and PPS sequence to prepare a card for T=CL data
exchange.
ISO14443-4_Init
Initialize the T=CL protocol. The intent of this command is to configure the protocol for
data exchanges. This is necessary if a card was already activated and configured for
doing data exchanges without using the ISO14443-4_RATS_PPS command.
