How it works...
All Smart shopping carts in the supermarket are registered in supermarket database and have a unique id number . The process that takes place in a cart when a customer picks up a cart and pick up the good can be stated as follows.
The shopper just have to scan the item before adding it into the cart.
Then the price of the item will be added to the current bill by reading tag on the item.
Then the billing will be done automatically.
Shopper can scan and remove any item ,the item will be removed from the bill also in our system
Customers can’t put/remove an item without scanning it will be monitored in our system.
This will be done by using the laser beams on the surface of the cart and weight sensors at the bottom of the cart.
Customer can release the shopping cart by paying the bill at the exit .There are 3 payment methods,
cash payment
credit/debit card payment
online payment using mobile/web app
