A friend of mine is opening a small cafe and obviously needs to have some form of cash register. Since a POS system seems easy to use being its touchscreen and the POS software has inventory and prints receipts, integrated with credit card purchasing, etc it seems a logical way to go. But, the owner is not technical at all. I am technical but have no experience in anything to do with POS systems, credit card systems.
Can anyone recommend what it is I should be interested in researching? I see with the Android tablets there is POS software you can use, that is cloud based. What does that mean specifically? The POS OS is based in the cloud and all transactions need to pass through that, including credit card information? What if the internet connection is down, how does one enter purchases?
Anyone that can give me some direction and an overview on the POS system and what I can do would help me out a lot.
