The current billing system uses RFID tags on which the billing data is stored and scanned at the billing counter for final bill amount. This system is complicated to use and requires the workers to take special training in order to use it correctly. The data is overwritten every time the RFID cards are reused, thus there was no way for data storing and thus no analysis can be done for improvement of the sales. Moreover there is no system which records and keeps a track of available quantity of the product.The system that we are proposing is QR based billing System. In this system users will be given a Q.R. token which they can use to load items on it. The data will be scanned from the item Q.R code and will be written in the user’s Q.R token.This token will be scanned at the bill counter and bill will be generated which will contain all the information related to the purchase.This system is connected to a centralised database and the billing history is updated in real time.Thus we are able to do the analysis of the data and we can pull out the records of any day at anytime for prediction of required stock or profit maximisation.
