Description
MFP_ProximityCheck performs the complete MIFARE Plus proximity check between MIFARE
SAM AV2 and the MIFARE Plus PICC. It performs the PPC, the one or more PC’s and the VPC
command.
As this is the X-mode command, the proximity time measurement is handled by a MFRC52X
reader IC time-out. The reader IC will use the ISO14443-3 minimal frame delay time, as a
time-out value for the PICC response to the MIFARE Plus Proximity Check command(s) sent.
In case the proximity check is executed with an MFP authentication, the MAC
session key of this authentication will be used for the MIFARE Plus Verify Proximity
Check (VPC). The command also foresees random VPC processing as
recommended in some cases for privacy reasons.
MFP_VirtualCardSupport sends as many MIFARE Plus VCS and VCSL commands to the
MIFARE Plus PICC as specified in the command.
MFP_VirtualCardSupport accepts up to 5 command sets. MFP_VirtualCardSupport returns the
MIFARE Plus PICC responses to the corresponding VCSL commands.
A command set is made of commands. For each command the key duo is specified (i.e. the
SAM key to be used for MAC and the SAM key to be used for ENC) together with the VCIID to
be advertised by the SAM to the MIFARE Plus PICC. Given a command set, sizeof(command
set)-1 VCS commands are sent with one concluding VCSL command.
MFP_SelectVirtualCard sends a MIFARE Plus SVC command to the MIFARE Plus PICC.
If no successful entry for this IID can be found (from MFP_VirtualCardSupport processing), the
SAM will still send an SVC command (with random MAC) to the card.
On successful execution (both valid and invalid IID), the internal VC table is invalidated. Note
that MIFARE SAM AV2 does not support multiple VC selection protocols to be executed in
parallel. The user needs to ensure the VC selection is completed before starting another on
any of the LCs, as starting VC selection with SAM_VirtualCardSupportMFP or
MFP_VirtualCardSupport will also invalidate the existing internal VC table (if any).
