I am a developer and would like to make life a little easier. I develop in both Linux and Windows but for this purpose I want to add a feature to my Linux POS. I would like to have the total sale amount automatically sent to the android device with Square on it. This way the user need only hit the charge button and insert the card. They do not have to enter the amount of sale at all. I have not found a way to do this. I could use a little help.
