German grocery stores experiment with payment by fingerprint
The tension level at the grocery store checkout sometimes rises when a customer needs extra time because they have no cash and therefore have to pay with a bank card.
This is especially true in Germany where there is almost always a line at the cash register and it's standard for customers to have to bag their own groceries. Some supermarkets in the country are working to remedy this problem by using a fingerprint scanner to verify identity and make the electronic payment.
A pilot project at a supermarket in the Rewe chain is under way near Cologne to test the viability of implementing the payment method in all Rewe affiliates in Germany. The comprehensive affiliate biometric payment method, as it is called, has a 'handy' advantage, said cashier Helga Gerth.
