Biohacker..Hannes Sjoblad from BioNyfiken (network based in sweden)

In feb 2015, 300 people volunteered to have NFC (Near field transmission) inserted between their index finger and thumb.

Stored Information like : House keys code, car key code, shop memberships, business card.

Cabapale of much more.

It is also available online (see picture) for $100 on the wesite dangerousthings..(at your own risk)

It can read/written with any RFID devices. Also has a mobile application!

What is the future of this chip?

Example: 'Limitless', a TV series where the guy discovers mysterious drug called NZT-48 which opens the full possibility of his brain and gives him perfect recall of everything he has ever read, heard, or seen. 

Maybe this chip could have a similar future..where you could have a control of drugs on you hand..

you could just run a finger across your hand and increase or decrease the effect of drugs on your brain.
