NTAG203 IC provides full compliance to the NFC Forum Tag 2 Type technical specification (see Ref. 9) and enables NDEF data structure configurations (see Ref. 10).

Anti-cloning support by unique 7-byte serial number for each device

32-bit user programmable OTP area

Field programmable read-only locking function per page for first 512 bits

Read-only locking per block for rest of memory

The anticollision function is based on an IC individual serial number called Unique IDentifier. The UID of the NTAG203 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3

An intelligent anticollision function according to ISO/IEC 14443 allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field
