CryptKey is a mobile application, and the first of its kind. It provides an easy to use secure communication service with built-in end-to-end encryption and state of the art security features. Our app goes far beyond conventional design by introducing an enitirely new element of technology into our security architecture called 'bio-hacking'​. Crucial to this design is a tiny RFID transponder implant, easily inserted into the web of the hand between the thumb and index finger, and readable from any NFC enabled mobile device. This permanent attribute, which requires no battery, then acts as a convenient wireless form of physical authentication between the implanted transponder and any NFC enabled devices. When used in conjunction with our app, nobody can access your data except you.
