6mm On-Metal PCB NTAG424

  • Extremely small form factor
  • On-metal capable
  • Authentication NTAG424 chip
This is a round 6mm diameter PCB (printed circuit board) NFC tag. Supplied with a genuine NXP NTAG424 DNA chip. This tiny tag is supplied with an on-metal ferrite barrier and adhesive, so that this tag can be stuck onto both metal and non-metal surfaces. Thickness of 0.85mm. Supplied as individual units.

Designed specifically for integration into jewelry and watches but would suit applications where space is extremely tight.

Scan Distance on this tiny tag is extremely short. It is possible that some Android phones - particularly with a case - will not be able to scan at all. This tag is not designed for customer facing use cases but rather as security integration where the person scanning will know how and where to scan - or be using a higher powered USB reader. It will scan with a very carefully positioned iPhone, but touching is almost certainly required.

Note that the NTAG424 is an advanced chip that requires specialised software for encoding and verifying the anti-counterfeit features. Usual NFC mobile apps cannot encode these chips to work with authentication. Ixkio tag management users can use the ixkio mobile app to encode for both redirect or API with full authentication.

We can provide high-speed encoding services for these tags for ixkio users and in some cases other verification systems.
