More Details

WARNING This device is definitely a dangerous thing. While the xIC transponder device has undergone several quality checks during manufacture and has been put through a battery of tests with various private labs, it has not been tested or certified by any regulatory agency for implantation or use inside the human body. Use of this device is strictly at your own risk.

The xIC is an ISO/IEC 15693 I-CODE SLI RFID chipset encased in a 2x12mm cylindrical USP grade lead-free borosilicate biocompatible glass housing. The xIC can be read and written to by many types of 13.56MHz RFID systems that use the ISO15693 standard.

Limited NFC compatibility

While not truly NFC compliant, the xIC does have limited NFC compatibility with certain NFC enabled Android devices such as the Samsung Nexus S, Samsung Galaxy Nexus, the Nexus 7, the HTC Amaze, etc. as well as Windows Phone powered devices such as the Nokia Lumia 920. These phones use NXP reader chips to power their NFC capabilities, and this chip comes with the ability to read some non-NFC compliant tag types. If your phone has an NXP reader chip, it may also be able to read and write to the xIC. Certain devices like the Google Nexus 4 phone and Nexus 10 tablet do not use the NXP reader chip and can not read from or write to the xIC. Check out our NFC compliant implantables page for fully NFC compliant options!

Important Things To Know

How/where are x-series tags installed? Aftercare? What to expect?
hand nervesOur x-series transponders are typically installed into the webbing between the metacarpal bones of the index finger and thumb, resting parallel to the index metacarpal. The reason they are installed in the hand has to do with the extremely short read range of x-series tags and the typical use case being some form of access control where the tag must be presented to a fixed reader of some kind. The suggested placement within the hand was chosen due to the lack of major nerve bundles or blood vessels running through that area.

Piercer installing x-series transponderAchieving a safe installation definitely requires a steady hand and experience performing aseptic procedures. Dangerous Things prefers our customers locate one of our professional body piercing or body modification partners to complete the installation of this product. If no partners are available in your area, you should be able to follow this guide to finding a professional in your area who is willing to assist you.

You have questions! That’s understandable. The short answer is; it’s all good. If you’re looking for more specific answers, we have an extensive FAQ page that deals with many of the most commonly asked questions regarding installation of our x-series transponders.
Practical read range/performance expectation
magnetic-fieldPassive RFID and NFC tags are magnetically coupled devices that power themselves and communicate data over a shared magnetic field the reader generates. This means their effective read range and performance depends entirely on how well the antenna coils of both the tag and reader couple with each other. This typically means the shape, size, and orientation of both antennas must be complimentary.

Unfortunately, most reader devices, including mobile phones, typically have antennas designed with thin PCB traces made into blocky rectangular shapes that lay along a flat plane. These antenna designs are great for coupling with and reading large flat label tags, credit card style tags, and access cards which also share this antenna shape, but they have a hard time coupling to the very small cylindrical antenna coil inside our x-series tags. Most mobile phones and reader devices have a “sweet spot” or two that must be located and used each time to get consistent results. Other devices, such as the Samsung Ezon electronic deadbolt lock, sometimes use wire wound coil antenna loops inside, which work much more reliably with small glass tags like our x-series tags. You should not expect your USB reader or mobile device to achieve the same read range with our x-series tags that you normally get with a label tag or card style tag. Here are some example videos detailing typical read performance and how to find that “sweet spot”.

How x-series antenna geometry affects performance

Tag testing process, return policy, lifetime warranty
Testing Process
Our x-series tags come pre-loaded inside injector systems with steel needles and cannot be read while inside the needle. Because of this, we perform a full test on every x-series tag before it is loaded into the injector assembly and sterilized.

Return Policy
All sales of this product are final and no returns will be accepted. We keep tight control over chain of custody on this through manufacture, sterilization, and shipment. We would not want to re-sell something that has been returned, and you probably wouldn’t want to buy one either… so before you purchase, do your research and be sure you know you’re getting the correct product, know it’s compatibility/performance/limitations/etc.

Lifetime Warranty
If you do purchase one of our products and experience a failure, we offer a full lifetime warranty on all of our products. You will need to return the product for testing and analysis, and if it is malfunctioning, we will ship you a replacement free of charge.
