NFC Forum Tag 2 Type compliance
NTAG213 Chip provides full compliance to the NFC Forum Tag 2 Type technical specification and enables NDEF data structure configurations.
Security
- 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
Cascaded UID
The anticollision function is based on an IC individual serial number called Unique IDentifier. The UID of the NTAG213 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3.
Anticollision
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.
