You ever get to the supermarket and realise you’ve forgotten your money or credit card? The trip home is then filled with self-recrimination about one’s own stupidity and how so much more precious time will be wasted just to fill the fridge and keep everyone fed.

For a mere EUR 249, you can order the “wallet of tomorrow”, a biopolymer implant said to allow users to just wave whatever body part contains the unit at the checkout chip reader. The company even suggests that prospective payment cyborgs can bypass their slice-happy surgeons and have the device inserted by a “professional body modifier”. So someone trained in the piercing arts?

The supplier’s website lists European countries where residents can use the payment system. This should be quite the hit for nudists and other people who hate pockets.
