My general question is, what do gas-station POS machines do differently than other retail/restaurant POS systems in regards to specific-amount cash sales? Example, walking into a Chevron and saying “Give me twenty on pump four”? I haven’t seen a clerk divide requested amount by $/gal and input that into the machine, so I assume the machine has the functionality to do this itself.
My specific question is, can someone tell me if I can get this functionality from a readily available app? Or is this something any POS can do and I’m missing how to do it entirely?
I ask because I’ve been looking for a POS app for Android that will handle keeping records for the small business in which I work. We are a small retailer of biofuels, and being small, we don’t have/cant afford a gas station-style POS machine. Having something that will work on our cheap Android tablet will help immensely, as we currently do all our record keeping by hand on a ledger.
