Which workstation "Cashier" to choose for cash register?

Question

QR codes

Good day!
Search engines no longer help me.
I am looking for an workstation for cashiers in the cash register (where they pay for utilities)
At the moment we use from the contour of the workstation "Cashier" which God knows in which 2000s it was written.
In search engines, there are many cash register applications only for retail, which does not suit us.
The main task is to minimize manual input and eliminate human factor errors and speed up everything by reading a QR code from receipts.
"Stack" and "RCC Soft" do not offer
I will be glad to read your suggestions!
