What is TagTamper?
There are two ICs from NXP with the name “TagTamper”, which are NTAG® 213 TagTamper and NTAG® 424 DNA TagTamper. Both ICs feature a novel tamper evidence function for identification of unauthorized access with its different design of IC structure. Such solutions based on TagTamper IC works without a dedicated App on the NFC mobile phone.
What is the difference between NTAG®213 and NTAG®213 TagTamper
There are 4 connection pads within NTAG® 213 TagTamper IC, compared to 2 connection pads with NTAG® 213. Such difference enables the design of an extra antenna loop for the RFID tag or label, which this additional loop acts as Tag Tamper detection wire.

How NTAG®213 TagTamper works
Typically, the tags are used to detect the opening of the packaging. The antenna structure of NTAG® 213 TT tag can be seen as two parts:
1 The main antenna loop to transmit radio waves between the RFID reader and NTAG® 213 TT IC.
2 The detection loop or detection wire. In case of an open or break of detection wire, the NTAG® 213 TT permanently stores this change. The information status of the Tag Tamper wire can be mirrored in ASCII code into the user memory and subsequently reported to the cloud.
The NTAG 213 TagTamper is fully compliant to NFC Forum Type 2 Tag and ISO/IEC14443 Type A specifications.
