More Details

WARNING This kit definitely contains dangerous things. While the xBT (LifeChip) 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 xBT kit contains the xBT chip and all the sterile procedure materials required to perform installation. The xBT chip is made with 134kHz FDX-B compliant Bio-Thermo LifeChip, which is encased in biologically safe 2.4×14.5mm cylindrical borosilicate bioglass tube and shipped in a sterilized injection assembly. The xBT reports a simple ID number which works with any FDX-B reader, and can also transmit temperature sensor data to a compatible Bio-Thermo reader.

The xBT chip is not an NFC device!
Halo ReaderTo read the xBT chip and get temperature data, we suggest using the Halo scanner from Micro-ID.

Testing process, return policy, lifetime warranty
Testing Process
Our x-series chips come pre-loaded inside injector systems with steel needles and cannot typically 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. We have also conducted several tests on our x-series chips and cataloged those tests here.

Return Policy
We offer a 30-day money back guarantee! Read all about it on our return policy page.

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. Read all about it on our warranty policy page.

Practical read range/performance expectation
Passive RFID and NFC chips 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 labels 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 chips. 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 transponders like our x-series chips. You should not expect your USB reader or mobile device to achieve the same read range with our x-series chips 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”.

The xLED can help! The xLED is a diagnostic device that mimics the x-series antenna coil winding and shows you the best possible location and rotation/orientation for holding your x-series transponder up to any reader. That’s why we include it in our deluxe bundle!

How/where to install the xBT tag? Aftercare? What to expect?
Typically, our x-series transponders are installed into the webbing between the metacarpal bones of the index finger and thumb, resting parallel to the index metacarpal. However, the xBT’s thermal sensor provides the most stable output when installed away from extremities and closer to the core of the body. Temperature in the hands and arms can fluctuate rapidly with changes in surrounding ambient temperature, and are not ideal for recording stable thermal readings.

The best installation location for the xBT tested so far has been in the skin near the arm pit, but not actually in the fold of the arm pit. For example, the area on the inside of the upper arm which rests against your torso when your arm is down would work well. Similarly, the torso area just under the arm pit which is completely covered when the arm is down, is also an acceptable location.

For aftercare information and what to expect, please read our X-Series FAQ page.

How does BioBond anti-migration coating affect removal/replacement?
BioBond is a porous material that, when applied to the bioglass encasement of the chip, forms an “anti-migration cap” which promotes tissue growth throughout its porous structure. The goal is to secure the tag and stop it migrating by literally letting the body grow into it to hold the chip in place.

The xBT was designed for use in animals by Destron Fearing. The reason why the BioBond coating is necessary has to do with animal (dogs, cats, horses, etc.) physiology, as well as the method and care taken during placement. Our other x-series products do not have this coating in order to facilitate easy removal or replacement. Once tissue has grown into the BioBond coating around the xBT tag, removal or replacement of the xBT will be extremely difficult, but not impossible.

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.
