The xNTi is a subdermal transponder and equipment for installation. xNTi Implants can interact with NFC type 2 compliant Mobile devices, readers and locks. The Implant was successfully developed by Dangerous Things as a crowdfunding campaign in 2014, and is now available to the average consumer.
This is not a toy. It would be wise to know compatible products and applications of the tag.

The xNT tag is a NTAG216, NFC type 2 compliant, 13.56MHz ISO 14443A chip encased in a 2 x 12mm cylindrical Schott 8625 bioglass tube. The bioglass tube is laser sealed and tested before the entire injector assembly is sterilized with EO gas.

The Full datasheet can be found here and should be read by anyone considering this.
The kits contains

1 sterile injector assembly, pre-loaded with an xNT tag

1 single use ChloraPrep SEPP 0.67ml applicator

1 sterile gauze pad for post-injection wound care

1 sterile expandable-fabric adhesive bandage

1 pair of non-sterile, non-latex procedure gloves


Instillation of the xNT should not be attempted by any untrained and/or inexperienced individual. We expressly indicate that this should be installed by an experienced body piercer/modifier or medical professional. We cannot stress this enough.

The xNT is loaded into an injector assembly for ease of installation.

Hand web piercing has been in practice by body modification artists worldwide and typically the xNT is implanted into the webbing between the thumb and forefinger. This location is chosen for a variety of reasons
- The implant can be pushed to the surface for a better read range
- The location is cushioned by protruding metacarpal bones
- Importantly, there is a lack of major nerve bundles or blood vessels through the area
Considering it is common for xNT implants to replace a set of keys or interact with a mobile phone - this place is recommend for frequent use.

Dangerous Things has collected a map of experienced professionals HERE and has developed very comprehensive professional installation guide here.

Anecdotally, I’ve personally had 15+ piercings and this was the least painful by quite a margin.


Aftercare for a xNT is extremely easy compared to a piercing and more akin to birth control implant. An open wound healing around protruding metal increased infection probability significantly. With a professional, a xNT installation can be over in seconds with the wound sealed within hours. After 2-4 weeks the transponder is encapsulated in fibrous collagen, within a month migration is no longer a concern. The point of installation may be swollen for 24/48 hours and/or bruised for upto 72 hours. For up to 12 hours momentary tingles, inching or pinching is normal as nerves heal.

RFID waves have read difficulties with metal surfaces, for this reason Dangerous Things performs full tests on the tags before they are loaded into the injector assembly and sterilized. They are not readable whilst within the steel needle. Dangerous Things keeps tight control over chain of custody on this manufacture, sterilization, and shipment.
