8.8 Command set
The ATQA and SAK are identical as for MIFARE Ultralight (see Ref. 7 “MF0ICU1
Functional specification MIFARE Ultralight”). For information on ISO 14443 card
activation, see Ref. 3 “
ISO/IEC 14443 PICC Selection”. Summary of data relevant for
device identification is given in Section 8.9 “
Summary of relevant data for device
identification”.
The NTAG203 comprises the command set as described in following chapters.
8.8.1 REQA
Description: The NTAG203 accepts the REQA command in Idle state only. The response
is the 2-byte ATQA (0044h). REQA and ATQA are implemented fully according to
ISO/IEC 14443-3.
