Authentication Pack

  • NTAG424 authentication chip
  • Variety of shapes and sizes
  • Pre-encoded or unencoded
The authentication starter pack is designed for testing and development of these more advanced anti-counterfeit NFC tags with NXP's NTAG424 chip. The pack contains the most popular stock items including garment tags, labels and tamper stickers.

The tags are available with or without encoding as follows :

Without Encoding
The chips are supplied in factory state so that you can test and develop encoding. Note that you cannot encode these tags with the usual NFC apps on a mobile phone. You need to either develop your own specialist encoding software or test with NXP's TagXplorer desktop software (USB reader required). To be clear - it's not easy to encode NTAG424 tags and you will need to have strong technical skills and a good understanding of how encryption works to do so.

With Test Encoding
We will pre-encode and lock the tags so that you can test scan the different products. All the tags will redirect scan through to a live test website (authnfc.com) and will authenticate using our ixkio tag management platform. The destination pages have been protected with ixkio's traceback code to provide a full redirect demonstration. Each tag will also display product code and product name on scan, dynamically provided by ixkio, so you can identify each tag. Test encoded tags cannot be re-encoded.

Additionally, the Test Encoded pack also includes two tags encoded to go through to a live test website via the ixkio platform and dynamically display an NFT (polygon blockchain).

This pack contains the following:

Using NFC Tamper Labels

There are two main categories of NFC tamper labels - Destruct type (which stop working on tamper) and Detect type (which continue to work but can tell if a tamper has been made). Destruct labels have two sub-types : scratch and peel. Detect have two sub-types : break and capacitive. 

Tamper tags don't like movement. They work best on firm, solid and non-flexible surfaces such as glass or rigid plastics. 

Scratch Tamper

Scratch tamper tags are designed to disintegrate on an attempt to remove. The tags must be attached to a smooth, clean surface. If you are testing, give the label plenty of time (ideally 24 hours) for the adhesive to get a good grip. An attempt to remove will chip away at the tag and destroy the antenna. These tags can be placed behind other labels. 

Peel Tamper

Peel tamper tags have two layers which are designed to separate when an attempt is made to remove. The tags must be applied to a smooth, clean surface. As with scratch tags, give plenty of time for the adhesive to reach full strength before testing removal. On removal, the top layer will separate from the base layer destroying the antenna and preventing the tag working.
