28mm Tamper Tag NTAG424

  • NTAG424 chip
  • Peel Tamper - destruct on remove
  • Reliable scan distance
This is a round gloss white tag with 28mm diameter and a thickness of 0.35mm. This tag has a strong adhesive and is supplied with a genuine NXP NTAG424 authentication chip.

These tags are supplied on reels for larger quantities and in strips for smaller quantities. Ideal for customers who would like extra protection of their items. This peel tamper tag has two layers and is designed so that an attempt to remove the tag will result in permanent damage and the tag will no longer work. The top layer will remove, leaving part of the antenna on the bottom layer.

The use of NTAG424 authentication will prevent the digital copy of the tag to prevent counterfeits. The tamper function will prevent physical movement of the tag. The combination creates a strong and effective anti-counterfeit solution.

Note that the NTAG424 chip is an advanced chip which requires specialist software both for encoding and for verification to use the anti-counterfeit features. You cannot encode these tags for authentication using a mobile phone. Please contact us before purchasing if you want to use authentication tags but aren't sure how to start.

These tags are compatible with the ixkio tag management platform and can be encoded Seritag for use with the platform.

Not for use on metal surfaces. We recommend testing on your particular product material to ensure that the bond is strong and the tamper function works effectively for you. When testing, leave the tag for as long as possible for the adhesive to reach maximum strength before testing removal.
