In a super market,
will enable the client to put any item into the cart and automatically scan it.
Total bill can be done there also.
This can be barcode
or RFID.
This can save the
cashiers (Maybe some will be left for cash clients and to solve issues).
The client will of
course be able to remove an item/items from the cart.
If the cart will also have a display on it, the store can advertise items
on the display according to the clients scanned products
