I have computer chips in my hands. The tiny (2 by 12 millimeters) glass ampules are nestled just under the skin on the back of each of my hands and were implanted by a local body piercer several years ago.
The chip in my right hand is a near-field communication device that I scan with an app on my smart phone to access and rewrite the information I have stored on it. It can contain a minuscule 888 kilobytes of data storage and only communicates with devices less than four centimetres away. In my left hand is a chip designed as a digital verification device that uses a proprietary app from the developer Vivokey.
