Project definition:

Cashier takes time to billing ,so long queues at the counters in supermarkets. So that shoppers have to wait lot of time near the counter.

Solution:

Introducing smart shopping cart with automatic bill system

Problem:

• Cashier takes time to billing ,so long queues at the counters in supermarkets. So that shoppers have to wait lot of time near the counter.

Target audience(buyers/users)

• Supermarket Management
• Regular shoppers

Solution:

Introducing smart shopping cart with automatic bill system

• The shopper just have to scan the item before adding it into the cart.
• This cart carries its own scanning device as a part of the cart.
• Then the billing will be done automatically.
• So that customer can pay the bill at the dedicated exit.
• Shopper can't put an item without scanning ,it will be monitered in our system.
• Shopper can remove any item ,the item will be removed from the bill also in our system

Further into problem:

• Shopper have to read discount flyers at shop and it takes time.
• If shopper can notified about discounts before the going to supermarket both audience are benefited.
• Online-ordering system(home delivery /order before you go to supermarket then just pay and take on the way home(No delivery charges))
• Checking price list before go to the supermarket .
• Make the to-buy-list before go to the supermarket.
• Misplacement of bills (Method to save recent transactions)
• Vouchers/tokens order system.

To solve that problem we are going to introduce an app.

Features of our app-:

• Customer User Account
• Price lists
• To-buy lists/online ordering
• Discounts/Promotions notifications
• Recent shopping activities

Solution Architecture :

The following diagram depicts how the major 3 sections are connected.

When designing the smart shopping cart, attention was paid to following aspects.

• Customer's convenience
• Reliable monitoring of the customer

1)For Customer's convenience:

• The procedure the customer has to follow is not much deviated from the traditional method used in super-markets.
• If customer forgets to scan it, he would be reminded (with the use of an alarm)
• Multiple payment methods

2)Reliable monitoring of the customer:

The following situations are handled using a combination of weight sensors and laser sensors.

- customer add/remove the item to the cart without scanning: Laser interrupted & weight in the cart does not match the calculated weight in the bill

- customer scanned the item ,but not added to the cart : Laser interrupted & weight in the cart does not match the calculated weight in the bill

Two way monitoring system (laser and weight) therefore increases the accuracy of the shopping process.
