Integrity mechanism
Parity, CRC
Response
16 Byte Date
Description: The READ command needs the page address as a parameter. Only
addresses 00h to 29h are decoded. For higher addresses, NTAG203F returns a NAK. The
NTAG203F responds to the READ command by sending 16 bytes starting from the page
address defined in the command (e.g. if ADR is ‘03h‘ pages 03h, 04h, 05h, 06h are
returned. If ADR is ‘29h’, the contents of pages 29h, 00h, 01h and 02h is returned).

Integrity mechanism Response
Parity, CRC
Passive ACK, NAK
Description: The HALT command is used to set already processed NTAG203F devices
into a different waiting state (Halt instead of Idle), which allows a simple separation
between devices whose UIDs are already known (as they have already passed the
anticollision procedure) and devices that have not yet been identified by their UIDs. This
mechanism is a very efficient way of finding all contactless devices in the field of a NFC
device. Even with incorrect parity value, the HALT command will be fully functional.
