NTAG 213 and NTAG213 TT

Compared with NTAG 213, NFC anti-counterfeiting label NTAG213 TT provides extended functions and provides additional advantages for smart packaging and brand protection.

The NTAG 213 TT new tag tampering function is used to detect the status of the tag tampering line during startup. If the detection wire is open, NTAG 213 TT will permanently store this event. The information status of the tag tampering line can be mirrored to the user memory containing NDEF information in the form of ASCII code or can be read by a dedicated command

Further provide improved original signatures on NTAG 213 TT, which can be programmed and locked during tag initialization. NTAG 213 TT fully complies with NFC Forum Type 2 Tag (Ref. 2) and ISO/IEC14443 Type A (Ref. 1) specifications .

Communication with NTAG 213 TT can only be established when the IC is connected to the antenna. When the NTAG 213 TT is located in the RF field, the high-speed RF communication interface allows data transmission at a baud rate of 106 kbit/s.

NTAG 213 TT provides specific functions designed to improve integration and user convenience. The fast read function allows scanning complete NDEF messages with only one FAST_READ command, thereby reducing overhead in high-throughput production environments. Improved radio frequency performance allows greater flexibility in the choice of shape, size and materials.

In terms of security, the manufacturer writes a 7-byte UID for each device. One-time programmable bit pre-programmed function container, field programmable read-only lock function, pre-programmed ECC-based original signature, provide the possibility of custom and permanent lock 32-bit password protection to prevent unauthorized memory operations. The tag tampering message programmed by the customer is shielded until the tampering event is detected after startup.


Contactless data transmission and supply energy 13.56 MHz operating frequency 106 kbit/s data transmission 16-bit CRC, parity, bit encoding, bit count data integrity. The working distance can be up to 100 mm (depending on various parameters such as field strength and antenna geometry). 7-byte serial number (according to ISO/IEC 14443-3 cascade level 2)

UID ASCII mirror for automatic serialization of NDEF messages. The automatic NFC counter is triggered when the command is read, and the NFC counter ASCII mirror is used to automatically add the NFC counter value to the NDEF message. The label tampering function detects whether the label tampering line is opened after startup. If a tampering event is detected, the tag tampering message ASCII mirror will copy the customized tag tampering message to the NDEF message. Based on the original ECC signature, it provides the possibility of customization and permanent locking, fast read commands, true collision avoidance, 50 pF input capacitance.
