Traditional canteens are based on pen-paper records, cash, manual calculations and manual record keeping of credits which in today’s time in an inefficient way to operate a business. The existing system lacks data integrity due to the use of books/files to store entries as these may be altered or easily misplaced and there aren’t any backups for such cases. 

The RFID canteen system will be able to overcome the disadvantages of the traditional canteens and also offer other advantages of automation like total bill amount, total profit/loss of the business, usage of food stock, an online menu, and the most trending food items, a much safer way to hold the money and as payments are online there will not be a need to provide change to the customers. Also records of past years can be easily stored and compared if needed without any hassle. 

All the user must get an RFID card by registering themselves with the manager and recharge the card with some amount. This card stores the mobile number of customer that will uniquely identify the customer, the card number and the balance in the card of the customer. If the card is lost or damaged it can be blocked by through the website or by requesting the administrator and a new card can be issued against the same mobile number.  To place an order, the student must provide the card to the staff taking the order who checks for sufficient balance and if found places the order.
