PROJECT

              "CONTACTLESS SMARTCARD WITH READER SYSTEM"

                A smart card is a card that is embedded with either a microcontroller and a memory chip or only a memory chip with non-programmable logic .In this project the state of the art security system ensures that while the system is in operation, only authorized personnel who enters into the proximity of the security check area can gain access into the high security risk areas. The authorization is carried out by exchanging a unique identification code. Here a typical frequency is generated by the transmitter module and the code is transmitted through frequency modulation. The receiver consists of a FM receiver and a microcontroller. The FM receiver is tuned to the required carrier frequency. The microcontroller in the receiver module is loaded with a program , which compares the code with the database stored in the memory. If it finds the user is authorized , it gives access otherwise it denies.
