Last night I was at an ice cream shop and they had this square checkout with stand. https://squareup.com/stand I was shocked at how easy the check out was from adding a tip to signing the receipt. This really is the future of registers! The video: http://vimeo.com/63784924 doesn't show adding a tip but all in all a very nice experience from a consumer perspective. It'll be a good day once these become more main stream.I love to see tech products that just make life easier!
