Aloha POS API

As Chadwick mentioned above SubtleData is a great choice to easily and cost effectively integrate with major Sharp pos terminal up-v5500 series manuals.I have experiencing trying to integrate with Micros it wasn't as bad as everyone said it would be you just have to be persistent with them for a response on the status of you application. Also you have to pay Micros per product integration i.e pay for the api for Symphony, Res, and E7 separately, so it can get expensive.

When I tried to integrate with Aloha or any NCR POS product I was almost instantly rejected by them so it didn't seem like they were too interested guess it depends a lot on what you plan on doing once you integrate. A lot of the smaller restaurant Pos systems were fairly friendly and approachable about integrating with them.
