Billing Automation for Supermarkets

With increasing access to supermarkets, the human resource required to maintain short queue times is ever increasing. This creates a need for automation in the billing system. A fast and simple solution is to decentralize the billing process. This project mainly aims at reducing queue times by scanning the items when being added to the cart by the customer, than being individually scanned at the billing counter. This is realized using Radio Frequency Identification (RFID) technology. Once the products are scanned using RFID reader and the bill is to be generated, the scanned RFID card numbers are wirelessly transmitted to the billing server/counter using Wi- Fi module. At the billing counter the scanned RFID card numbers are matched against a database and corresponding information such as the product name and product cost are retrieved. Once retrieved, the corresponding product costs are summed, the bill amount could be paid for using digital payment services. Once the payment has been processed, the customer receives an OTP that is to be used at checkout.
