This is an unevaluated tool because no one has used it yet. It was just released today. It is an iPad app with a Square credit card reader and it has the potential to simplify retail stores Point-of-Sales, and eliminate “cash registers.” A store owner would get to customize the touch screen to their store, making it dead simple to operate. Restaurants might even put one on each table allowing customers to order their own food. It’s a ingenious and elegant hack. I’d love to hear from anyone who actually uses one.
