You Still Have To Touch The Cup, Tho
-
Maybe buffets are goners, but Coca-Cola may have rescued the self-serve soda fountain. You know those "Freestyle" machines with all the choices on a touchscreen? They've made them contactless, operated with your smartphone, no app required. You put the cup in, you scan a QR code, the menu pops up on your phone, you select what you want, and there you have it. Okay, seems a little complicated, but you want your soda and you don't want to touch anything, so that's the best you can hope for. (Yahoo! Finance)
