6.1 T1T, T2T, MIFARE Ultralight, MIFARE Classic and MIFARE Plus tags
N
ote: all the Tags/Cards in this category are based on NFC-A technology, but they do not
s
upport the ISO-DEP Protocol.
MI
FARE Plus cards support the ISO-DEP protocol, but only when they are configured in
Security Level3, which is out of scope for this section.

1.1 Access through the [NCI] Frame RF Interface
[
NCI] allows the data exchange with tags T1T, T2T using the Frame RF Interface.
Most of the commands of the MIFARE Classic and MIFARE Plus can also be mapped on
the Frame RF Interface, but NXP decided to use a separate RF interface (TAG-CMD, see
6.1.2) because some MIFARE Classic commands are split in 2 steps (e.g. Authenticate
command) and have a tight response timeout (about 1ms) which can hardly be monitored
by the DH through the NFCC.
Here is a summary of the Tags/Card based on technology NFC-A which can be accessed
through the Frame RF interface

this parameter is not active in PN7150: it can be read/written, but PN7150 will always
behave with Bail Out in NFC-A, whatever the value written by the DH to that parameter.
