NTAG203 card is designed for NFC Forum type 2 tag applications. Such as WiFi protected set-up , call request , SMS, smart advertisement, goods and device authentication, Bluetooth simple pairing and so on.
RF Interface (ISO/IEC 14443A)
-Contactless transmission of internet data and still provide energy (no battery needed)
-Operating distance: up to 100 mm (determined by field strength and antenna geometry)
-Operating frequency: 13.56 MHz
-Fast data: 106 kbit/s
-High data integrity: 16-bit CRC, parity, bit coding, bit counting
-True anticollision
-7 byte serial number (cascade level 2 according to ISO/IEC 14443-3)
EEPROM
-168 bytes of total memory, divided in 42 pages (4 bytes each)
-144 bytes of user r/w memory area, divided in 36 pages (4 bytes each)
-Field programmable read-only locking function per page for first 64 bytes
-Field programmable read-only locking function per block
-32-bit user definable One-Time Programmable (OTP) area
-16-bit counter
-Data retention of several years
-Write endurance 10000 cycles
NFC Forum Tag 2 Type compliance
NTAG203 IC provides full compliance on 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 and every 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 all memory
Cascaded UID
The anticollision function will depend on an IC individual serial number called Unique IDentifier. The UID in the NTAG203 is 7 bytes long and supports cascade level 2 based on ISO/IEC 14443-3.
Anticollision
An intelligent anticollision function according to ISO/IEC 14443 allows to use more than one card from the field simultaneously. The anticollision algorithm selects each card individually and helps to ensure that the execution of your transaction which has a selected card is carried out correctly without data corruption as a result of other cards from the field.
