Billing System Based On RFID

  We usually come across areas where barcodes are used for product identification and billing. But these tags need to be visible and sometimes need double scanning. Also these cannot be used for card scanning. Here we propose a rfid based billing system. RFID tags are easy to scan. They are detected by scanner even if they are covered by something. They also avoid product theft since they can be detected at the facility gates. Our system proposes an Rfid based billing system where we use rfid technology for product billing purpose. Our reader gathers the id and sends it to microcontroller for processing, it is displayed on an LCD display. This data can now be passed on to the computer for further billing and procedure.
