Thousands In Sweden Have Implanted Microchips Under Their Skin

More than 3,000 people in Sweden have implanted tiny microchips beneath their skin to replace their credit card information, identification, keys, train tickets, among other everyday items, Agence France-Press announced Sunday.

The implant, which is about the size of a grain of rice, utilizes Near Field Communication (NFC) technology, also found in credit cards, debit cards, key fobs, and smartphones. This technology is considered “passive,” which means the microchip stores data that can be read by other devices but cannot read data themselves.
