Implantable technology is gaining popularity, seeing people insert microchips under their skin to unlock doors, tap on on public transport and to make contactless payment in shops.
Most chips weigh less than a gram and are about the size of a grain of rice. These tiny biopolymer enclosures contain a chip and an antenna that uses is near-field communication or NFC, similar to the contactless payment technology in a smart-phone.
Part of a movement known as biohacking, implantable technology shows no signs of slowing down as the relationship between humans and technology grows closer.
