Digital NFC CARD artist id card Anthony Antonellis has embedded an NFC-compatible RFID chip in his hand as a way of sharing his artwork with others.
The 1KB chip was implanted between Antonellis' thumb and forefinger and holds an NDEF message containing a URL that points to a website which hosts a small animated GIF image. The chip also contains the image as a downloadable file, says the artist, which can be read or replaced using an app.
