QERKO: Pay your bill from your phone

Recently I've used Qerko app, which is getting more popular in Czechia. You simply scan the QR code on your table and pay your bill, without necessity asking the waiter.

I love the idea, but when I firstly used their app I was so disappointed by its UI. So I decided to come up with own concept.

For illustrations I've used ManyPixels free library.
