Moon might be a good option for you. They offer prepaid, non-reloadable debit cards that are paid for in BTC. Best of all, there’s no KYC at all, and they can even be added to Apple Pay or Google Pay. I quite like it, I think it’s pretty neat. Source: over 1 year ago

OpenBravo POS used to be ok, it even worked with barcode readers. But you could also manually punch up a sales receipt and it would adjust on hand numbers automatically. But Open Bravo has moved on to a cloud paid model. However there a few forks from the before time, like Unicenta, but I've never used that one and can only vouch for what it was back in the day.

I would recommend going with https://opensourcepos.org/ or https://unicenta.com/. Source: almost 3 years ago

Unicenta works pretty well on a POS that I salvaged from a shop closure last year (no reason for doing so - just thought it would be cool to have one for the hell of it). Runs on Linux as well as Windows if you want to escape Windows Embedded 7. Source: almost 3 years ago

Looks like Unicenta is an alternative POS that can be self-hosted and is licensed as GPL-3.0-or-later. Source: about 3 years ago
