I have a brewery, taproom, and event space in my hometown that I've gotten open recently, and for now I am cash-only (I even bought an ATM that I surrounded with cabinetry, so it looks nice.)

We're headed to a public Grand Opening soon, and in working towards that while minimizing data surface area, I'd like to use a POS credit card reader that is as respectful of my customers data as possible.

I've whipped up a simple POS system on an RPi, and I'd love a CC reader that has a simple API or SDK so I can generate a bill total, and send that (only) to the reader to avoid manually entering data. It'd be nice to get a push back with a transaction outcome.

I don't really want to roll my own PCI compliant solution of course, avoiding device key injection and all that. I don't want to be a POS system vendor, just a small business that lets my customers make purchases conveniently without unneeded vendors monitoring their business with me.

I've only found once reader vendor (ID tech) that has a well documented SDK, and this domain is hard to search through SEO'd noise to find solutions. Are there any good options I should know of? Thanks!
