RFID is an acronym that means Radio Frequency IDentification. In short, RFID describes a method to identify something using radio energy. There are many types and flavors of RFID created by a huge range of technologies that can all be classified under the RFID umbrella. There are a few major segments, defined by the type of radio energy constructed; active, passive, and capacitive. Active devices are powered radio devices which communicate using the electric field, such as smartphones, ham radios, broadcast radios, etc. Passive RFID systems are magnetically coupled devices where a reader and tag use inductor coils. The reader creates a magnetic field and the tag inducts power from this field to power itself, and this magnetic field is modulated to pass data between reader and tag.
NFC is an acronym meaning Near Field Communication, which is a set of protocols that lay directly atop passive RFID standards. Therefore, all passive NFC tags are passive RFID transponders that conform to the NFC standard, but not all RFID tags fall under the requirements of the NFC standard.
So why would anyone want to implant one of these transponders under their skin? Amal Graafstra, our founder and CEO, explains his reason for implanting transponders and starting biohacking company Dangerous Things in this 2013 TEDx video.
Our x-series transponders are the most popular transponder implants because they are easily installed using an injection assembly (a needle). Because they are installed using a needle, we partner with professional body piercers to ensure our customers can get our products installed safely by a licensed professional in a sterile studio environment. Our flex transponders are more advanced, with better performance, but installation requires a medical doctor or a skilled and licensed professional body modification artist who is familiar with more advanced body modification procedures.
We’re sure you have plenty of questions about our transponder products, which is why we are constantly updating our transponder FAQ. Each product page also contains useful product-specific information, so be sure to read the product pages thoroughly.
