Re: Couldn't a Pi do the job these days ? @Roland5
So long as everything was made to be PCI compliant and the hardware requirements were doable then fine.
A few years ago the NCR tills at Tesco used to have a fault in the software. If you were in the middle of your scanning and pressed "Request Subtotal" the machine would crash and restart itself. I worked out what was causing it and told the friendly staff at my local store. The duty manager asked me to prove this to her satisfaction which I did to her amazement. She then tried it herself and the same thing happened causing much writing of notes. She then scanned all my shopping and overrode the price down for everything to a penny. She paid that herself and thanked me for my bringing it to their attention. I joked that I should have put some bottles of booze in the trolley before alerting her.
