RFID/Smart Card Based Mess Bill

The billing system presented is basically an embedded one. Here, the software using a Microcontroller
controls all the hardware components. The microcontroller plays an important role in the system. The
main objec
tive of the system is to uniquely identify and to make bill for a person according to his
menu order. This requires a unique product, which has the capability of distinguishing different
person. This is possible by the new emerging technology RFID (Radio F
requency Identification). The
main parts of an RFID system are RFID tag (with unique ID number) and RFID reader (for reading the
RFID tag). In this system, RFID tag and RFID reader used are operating at 125KHz. The EEPROM used
for storing the details has t
he capability of storing 256 person details at a time. The PC can be used for
restoring all the details of attendance made .
