Too.kn - Book a Tokan for social distancing

Here is an exploration for a token-based application to visit stores, during the ongoing pandemic.
It works as simple as search the store book the appointment and a QR code is generated.
This code is scanned at the entry and the store allows the customer.

The app is kept simple, with very minimal colours. And has fewer interactions to make the flow faster.

I would like to hear some feedback on the layout as I feel it's quite unconventional and distributed.
Also at times, I feel the colour composition is off.

Feel free to advise and comment.

Don't forget press "L" if you love it.
Thanks!
