I’ve seen a few retail shops and craft show vendors using their iPads (or iPhones) at checkouts. Attach a Square credit card reader, and you have an instant cash register. If that’s your setup (or if you’re considering that setup), have a look at this beautiful wooden stand by Tinkering Monkey. It pivots back and forth so both you and the customer can look at it, and they will laser engrave your logo on the stand.
I have no real need for this, but I kind of wish I did.
