Implantable Microchips

A Dutch entrepreneur has had two wireless computer chips implanted under the skin in his hands to allow him to store digital currencies like Bitcoin inside his body. Martijn Wismeijer is the founder of Mr Bitcoin, a company which installs and operates crypto-currency cash machines in and around his native Amsterdam and across Europe. This month he chose to undergo a painful procedure to embed NFC (near-field communication) chips under his skin.
