Abstract:
Radio-frequency identification (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almost-parallel reading of tags.
The tag's information is stored electronically. The RFID tag includes a small RF transmitter and receiver. An RFID reader transmits an encoded radio signal to interrogate the tag. The tag receives the message and responds with its identification information. Many RFID tags do not use a battery. Instead, the tag uses the radio energy transmitted by the reader as its energy source. The RFID system design includes a method of discriminating several tags that might be within the range of the RFID reader.
In canteen each table put one rfid reader the person is swipeing rfid tag display table number in chef room and put one keypad enter the number each number will be assign one item [idly, puri, tea etc] in canteen, enter number will display on LCD in cheff room .main advantage by using this project is to avoid long queue in cash counter and no need to carry cash all time and each table in canteen communicate by using RF system
