>Has anyone ever created an app where they duplicate a CC terminal in software? I'm assuming that the data transfer is tiny for a cc auth and it should be a fairly simple excercise, using some kind of comm toolkit, to put together the string, dial out and wait for the reply. The only part I don't know is the string format. Are there any common formats or ideally, a single data format to use? Thanks.

I would think this would be similar to a web commerce transaction. Is the charge from your service provider that much less if it comes in over a phone line vers the internet?
