It seems that people in Sweden are tired of carrying around wallets.
Thousands of Swedes have taken to getting chips implanted into their skins with the purpose of replacing all of their cash and credit cards. More than 4,000 people have undergone the procedure, which takes the chip, about the size of a grain of rice, and implants it into their hands.
The chips monitor health, and have even replaced keycards required to enter office buildings and apartments. The biggest feature, however, is the ability to pay at shops with a simple swipe of the hand. “It’s very Black Mirror,” says Swedish scientist Ben Libberton.
