In our changing society, we become more digital. Most people are used to paying with their cards and more and more places have a card-only policy. However, for elderly people this change can be challenging when they have trouble remembering all their pincodes and do not trust NFC payments. For this problem, a concept was developed.
The idea was a payment device of the size of a card holder. A wave on the screen indicated how much of the total monthly budget is still left and by scanning their finger they can see the exact amount left. Furthermore, the device can be used as NFC payment device, but the finger has to be scanned again before the payment will be completed, making the transaction more secure than current systems.
