Voucher app concept - Use voucher

Final shot of my voucher app concept! This is the flow a user will experience when using a voucher to pay for a product or service in the store/café/restaurant/etc.

I've designed it to be rather low-tech, with the user manually entering the amount to pay. Wouldn't design the app to rely on sophisticated technology - nothing wrong with being realistic, even though it's just an imaginary concept, right?! ;-)

Anyway, I've found inspiration for the design in various payment apps, and also tried to make it quite different from the experience of BUYING a voucher in the app to make it more understandable for users.

Hope you like it - would love your feedback :-)

All the best,
CJ
