Tribal Expression and Keith Kennedy are excited to announce that Tribal Expression is again offering subdermal NFC (Near Field Communication) microchips 


Tribal expression and Keith Kennedy have always been innovators both in piercing and in technology, dating back as early as 2006 Keith was one of the first professional shops offering RFID (Radio Frequency Identification) microchips Implanted under the skin.

At this time Keith and a few employees created a database system that would permit access control to the subdermal chip holders

Tribal NFC microchipIn 2006 we saw the massive potential for the technology, and continue to dabble in Implantable Access Control Technology.

Though at that time none of us was able to see the potential for Scanable Implantable NFC Microchips easily programmable via our cell phones.
These chips can store information like; Website; Contacts; Launch an Application; unlock your cell phone; unlock your home; etc.   All of this information can be rewritten hundreds of thousands of times on the transponder.

Skip ahead to 2016 and technology has advanced enough thanks to “dangerous things” a company that has pioneered NFC implantable tools, allowing us to again make this a retail thing.

The tag is a ISO/IEC 14443-A and fully NFC Type 2 compliant NTAG216 based xNT tag encased in a 2x12mm cylindrical USP grade lead-free Schott 8625 biocompatible glass casing, which is pre-loaded into a sterile injection assembly.  The xNT tag can be read and written to by many types of 13.56MHz RFID systems, and all NFC compliant reader/writer devices including USB devices and all NFC capable mobile phones.

Stuff that you can do with your subdermal NFC transponder

NFC / NTAG216 / 13.56MHz type RFID Technology is advancing rapidly, we are we are always looking for new devices and technology work with our implantable tags, we have seen padlocks, door locks, relays, with the simple controller and relays you can control almost anything.

Currently at the shop we are carrying the Samsung Ezon Smart Door Lock for sale, is highly reliable and compatible with our NFC Chips.


There are numerous applications available for download in the Google Play Store designed specifically for NFC or RFID applications, these applications will read and write NFC tags or chips.

These applications write information to your tag, so that when your hand and/or body part where the tag is placed. This will launch to a specific function on the phone
(i.e.) If you programmed in your V card full info.
Contact from your hand on the back of someone else's android device it would automatically launch asking them where they would like to save your V card information.
If you program in a website address, it will launch and take them to a website, if you would like them to download an app from app store you can program in the location and it will take them there for download.

You can add voice messages, you can add a voice clock so that whenever you touch the back of your own phone it tells you the time.
You can use it to lock and unlock your phone.
The android possibilities are endless.

Most of these applications in the play store are free, though, as we all know the best ones are not free and we highly suggest getting some of the paid applications.
I am personally a fan of  NFC Tools Pro!

We are currently selling the Samsung NFC Smart Lock at the shop, this is a robust block that works perfectly with our subdermal NFC transponder!!!!!!!!!!!!


Frequently asked NFC/ RFID questions

The xNT contains an NTAG216 chip which supports lock bytes and 32 bit password protection options.  Unfortunately, none of the NFC apps we’ve seen support dynamic lock bit setting or password support, so we wrote our own called Dangerous NFC!  This app will ensure your xNT cannot be accidentally or maliciously be forever locked into a read-only state.  Password support means you can protect your tag from unauthorized reading or let everyone read it but require a password to program or update your xNT.

What type of transponders do you carry?

xEM 125khz EM4102
The xEM is a low frequency 125khz transponder based on the EM4102 chip which has no user programmable memory or security features.  Each xEM tag is programmed at the factory with a unique ID that cannot be changed, and it works with common EM41xx based readers available through many hobby electronics shops and electronics outlets.  Several commercial systems can also read and work with the xEM tag, however we offer it as a “starter” implant for people new to RFID in general.  The xEM is low cost, simple to use, and we also sell an xEM Access Control unit that works beautifully with the xEM tag that enables hobbyists to cheaply and easily build simple access control type projects.

xNT 13.56mhz NTAG216
The xNT is a high frequency 13.56mhz transponder based on the NTAG216 chip.  The NTAG216 has 888 bytes of user programmable memory, 32 bit password protection security features, and is both ISO14443A and NFC Type 2 compliant.  You can use the xNT with both commercial systems that work with ISO14443A as well as NFC devices like mobile phones and new ISO14443A and NFC hobby electronics as well.  There are several hobby electronics readers and reader kits available, including one we sell, that work with Arduino and other micro-controllers commonly used by hobbyists and product engineers alike.

How is The Piercing / transdermal tag done?
The piercing itself is very simple most would compare it a regular body piercing and or is simple IV injection.  The procedure itself is about as minimally invasive is getting a needle and the wound itself has about the same healing time. Though the transdermal tag mild discomfort or a few days.
The tag will sit in the fascia layer between dermis and muscle, and it takes one to two weeks for the body to encapsulate it in fibrous tissue
The placement is generally between the four finger and thumb.

How tough are the Tags?
I personally have had a 125 kHz tag in since 2009 I have been through many bangs bruises, for MRI's and it still works just fine.  The manufacture has also put the text through some extensive testing, including crush testing, liquid nitrogen dunk testing, and vacuum and pressure testing.  In all cases, our glass implantable tags stood up to;

– 500N of force, maxing out the machine’s ability to produce additional force
– No glass degradation after exposure to 0.482mBar pressure (nearly perfect vacuum)
– No glass degradation and immediate function 5 seconds after removal from liquid nitrogen
– No glass degradation after exposure to 6 bar, or approximately 87psi of pressure

Q: Is it easy to remove or replace later?

A: The design of the x-series glass tag implantable transponders for easy removal.  Unlike animal transponders, we do not coat our implantable transponders with biobond or parylene, making removal easy.
