Qr Code Validation more safety COVID19

[RaviolPub]

Hi, would it be possible to print unique qr codes, similar to a voucher, that the customer can give to the barman who can validate with a qrcode reader? In this way it is possible to have a single cashier, and the bartenders do not have to touch the money, an extra security for COVID19

Thanks

The idea would be to associate and print a unique qrcode, which will be printed and delivered to the customer. The customer can show it to the bartender, who will verify the authenticity with a qrcodescanner and give the drink to the customer. A similar function to this service

It's possibile to add a similar function?
