We want to have a credit card reader created similar to "Square Reader".
We need a simple API interface to the reader that we will then use to connect to our applications. (We plan to do this ourselves, but there would definitely be additional work from time to time available if desired to assist with this.)
You may ask, "Why not use Square Reader or one of the others?" The answer is because they all charge 2% or more per transaction and we want to be able to take credit cards without additional fees.
