Any supermarket can be improved like this. At the customer service desk you can ask for a 'shopping screen'. As you walk through the aisles, it displays the products the nearest to the screen (RFID). When you see something you want, just touch the screen and it is added to the shopping list.
After
shopping you hand over the screen and you pay. You tell when you want the goods at your home and you go home empty handed.
Less stock, less shop lifting, less damaged goods, more convenience. You can leave your car at home, just take public transport or walk/bike to the shop.
A combination with ordinary shopping is also possible. Certain fresh goods or products you immediately need you can take home, the rest is 'shopped through the screen.'
After shopping you can check the status of your shopping on a website and change your mind. Order more or less, extra items, change the delivery day or time and so on. Your shopping history/habbits are stored, so you can easily shop for the same things as last time. In the end, you only go to the store for inspiration, try/taste new products and so on.
After I got this idea I found the No Shelf Supermarket idea and I improved this concept a bit with the comments on that one.
How should I improve the Idea's name?
