At it's simplest, I think the main issues would be: 1. a lock-down mode (kiosk) so that users could not access anything other than the checkout software 2. a barcode reader that provides input to whatever software is being used to connect to the Koha database -- I am not terribly familiar with the self-check functionality mentioned by Ryan Sipes in this thread, but if that works then (1) and (2) may be all that's needed, if RFID is not being used 3. It's possible something like this RFID programmer (http://tinyurl.com/o4dygcz) would work as a reader/writer. I honestly don't know what the standards are that are mentioned in the ad (ISO/IEC 14443 A and B). There are a number of these things on eBay, I just happened to pick the first one that seemed applicable. When/if we get to this for real we'll figure it all out. One of the things we really work at here at our library is reducing the footprint of our computer hardware, especially for systems used by the public, like a self-checkout would be. We've played with the Raspberry Pi (and Cubieboard) some, and generally feel it doesn't have enough firepower to be a satisfactory web browser, out-of-the-box anyway. A computer we do use more, clearly a couple of steps up from the Pi, is the Zotac. It has enough gas in the engine (sorry for the Americanism, I mean "power") for nearly everything we use it for, but we've also had some flake issues with HDMI output, so we're still cautious, but mostly we're happy with it. http://www.zotacusa.com/zbox-ad06-plus.html This computer has the advantage of having a "good-enough" CPU, RAM and hard drive, and there is no OS installed so there is no "penalty" for a pre-installed system that we need to just wipe out.

Unfortunately it seems that you need a system now, and anything we do won't be worked on until at least mid- late-2014. This is, however, a good discussion topic and worth continuing.
Would it be an accurate statement that the primary distinctive issues (as opposed to the usual issues with setting up a kiosk computer) that an open-hardware self-checkout machine would be need to deal with are:
- interacting with whatever device desensitizes security strips? - interacting with RFID pads?
