Our school was contacted by a Danish design company to create a merchant prototype for the payment card, Dankort, managed by NETS.
The assignment was to create a high fidelity prototype of an app-to-app payment system for small merchants like street-food and festival vendors.
In our solution, we made an easy-to-use system for tablets and smartphones. The system makes use of a so-called "Bumper" phone, which acts as a intermediate between the merchant and the customer. So when the customer wants to pay, he or she can simply hold their phone near the Bumper phone which completes the payment.
