An Artist Got an RFID Chip Implanted Under His Skin

The worst has happened! An artist, Anthony Antonellis just got an RFID chip implanted in his skin. The RFID chip is the size of a grain of rice and can contain up to 1KB of data. All you need is to approach your smartphone to scan the hand and discover content. For now, Anthony Antonellis is using it to display his favorite GIFS.
  
  
This experience can be scary because we can easily imagine the marketing excesses that could result if everyone starts to implement this kind of chip in their skin. Some say that it could store vital data, which would be effective in an accident for example. Some would say it is just a new way to be more "controlled" than we already are ...
So, for or against?
