SWEDEN (CBS) -- Many of us have a wallet full of plastic cards, credit cards, travel cards, membership card for fitness center and so on.
It can be difficult to keep track of all the cards so thousands of Swedes have replaced one or more of the cards with a microchip – which has been shot under the skin in their hand.
The chip is about the same size as one of the legs on a normal plug and you choose yourself, where you want the chip to be put. Typically, it is placed between the forefinger and the thumb – where you have a little slack skin.
The chip can in principle replace all the cards you want.
