The document describes a smart RFID card system that could replace the printed coupon distribution system currently used for food stalls at NIT Trichy. The RFID card system would use passive RFID cards with embedded codes, RFID readers connected over Ethernet to a central PC. This would allow transactions to be recorded digitally, eliminating manual counting of printed coupons. It would also support three user roles - shopkeepers, moderators to update balances, and students. The estimated total cost is around Rs. 5,000.
