But it goes beyond that. Your local chains make you go through a pre-installed POS for payment. Square disrupted the POS by setting it free inside the store, each store rep armed with their own POS running on a smartphone. Apple, by doing this has eliminated traditionally held notions of a POS altogether.

The POS now runs inside YOUR Smartphone, inside their app. You can browse the aisles, take all the time you need and when ready, check out with out having to wait in line (which you still had to, at your local chain) and with out needing to find a store rep. That is why I called it as re-inventing the checkout experience. It didnt merely parallel the existing POS experience.

A grocery store is different. It may process anywhere from 1 to 100 items per person, some of whose prices will depend on weight. Your local chains will probably always make you go through a pre-installed POS for payment and you will probably always appreciate that fact. The volume is high enough to benefit greatly from specialized tools.

Apple can do this because it sells low-volume, predictably-priced items out of its stores. Theft is probably deterred largely by the expense of the items they sell accessories for; far fewer of their customers will want or need to steal. This is the next step for Apple. The next step for your grocery is to identify items automatically, sort and package for carryout.
