More Details

WARNING This kit definitely contains dangerous things. While our chip implants have undergone several quality checks during manufacture and have been put through a battery of tests, nothing has been certified by any government regulatory agency for implantation or use inside the human body. Your personal decision to purchase and ultimately the safe use of these devices is strictly your responsibility and at your own risk. The xSIID is a next generation NFC compliant microchip implant which leverages the SIID, an innovative OEM module design from Dsruptive. The module houses both an NTAG I2C NFC chip and an LED indicator tied to the energy harvesting pins of the NTAG I2C. This design ensures the LED does not interfere with operation of the NFC chip and always receives filtered power output regardless of field variance. The xSIID comes in a variety of colors and offers the 1kB (888 bytes) user writable memory. You can store website URLs, contact details, or arbitrary binary data and share that with anyone who scans your xSIID with an NFC enabled smartphone!

xSIID Kit Contents

The xSIID kit contains the following products and materials, which are designed to enable you to bring the kit to a professional installation partner for installation.

  • 1 sterile injector assembly, pre-loaded with xSIID chip implant
  • 2 single use ChloraPrep antiseptic wipes
  • 1 sterile gauze pad for post-installation wound care
  • 1 sterile expandable-fabric adhesive bandage
  • 1 pair of non-sterile, non-latex procedure gloves

xSIID Kit Extras

The following accessories also come with the xSIID Kit. These accessories are “field detection” tools designed to assist you with identifying the type of readers you may encounter, but also the best location and orientation to present your xSIID chip implant to any reader to get reliable performance.

Our X Field Detectors (XFD) will show you the best position and orientation to present your chip implant to any readers of the same frequency, while our RFID Diagnostic Card will tell you all about the frequency and duty cycles of random readers you encounter in the wild.

Important Things To Know

Please expand the sections below to read up on things like performance expectations, return policy, installation procedure, etc.

The NTAG I2C chip used in the SiiD module we used to construct the xSIID implant has 2kB of memory, split into two large memory sectors. The problem is that the NTAG I2C chip is not commonly used by consumers, and at the moment there are no apps available that properly identify and read the entire user memory beyond 1kB. Please read this forum post carefully as it explains the issue and possible remedies; https://forum.dangerousthings.com/t/so-what-happened-with-the-2k-memory-on-the-xsiid

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 X Field Detector (XFD) can help! The XFD 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 are x-series chips installed? Aftercare? What to expect?
Our 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 chips 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.

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

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.
