29mm On-Metal NTAG213

  • High quality ferrite barrier for maximum scan performance
  • Reel based product for easy handling
  • Strong adhesive for on-metal applications
Normal NFC tags cannot be used on metal surfaces. For metal, you need a specialist on-metal NFC tag which contains an additional barrier layer. On-metal tags can work on both metal and non-metal surfaces.

There's a big difference on the market between the quality of on-metal products, with many have a very poor on-metal performance. For these 29mm white plastic face adhesive tags, we use the very best components and high performance ferrite barrier material for the most reliable scan performance.

Contains industry standard genuine NXP NTAG213 NFC chips for reliability and stability. Supplied on reels up to 1,000 units and on strips of 5 in smaller orders. Can be supplied by Seritag with ID and QR code printing as required. Also available as a special order with custom full colour artwork. Contact us for information.

Note that on-metal tags have a front and back. The adhesive side with the barrier material needs to be applied to the metal surface and the white/antenna side facing towards the scanner. If you applying the tags to the back of an object being applied to a metal surface, then you need a 'reverse' on-metal NFC tag.

On-Metal Tags Explained

Normal NFC tags do not work when placed directly onto metal surfaces. Therefore, when using NFC tags on metal you either need to create a gap of at least 0.5 cm between the tag and the metal or you can use a special tag - called an 'on-metal' tag - which has an additional ferrite barrier material between the NFC tag and the adhesive. 

On-metal tags will work on both metal and non-metal surfaces. However, on-metal tag scan distances always tend to be slightly less than standard NFC tags so unless you need tags that will (or might) go on metal, we would strongly recommend that you go with standard tags.
