Mobile RFID reader with database wireless synchronization

Using radio scanners to wirelessly identify consumer is not too complex in reality. The current form of this technology known as radio frequency identification, or RFID, has three building blocks: small tags built around microchips that carry a digital identification code; scanners also known as readers; and networking hardware and software to link scanners to computer databases. In this paper, we describe the implementation of a mobile RFID reader using a PDA, an OEM flash card reader module, RFID passive tags and a database. The reader opens a serial port and then reads a tag to use it as an index key in the database to access and show the record associated to the tag. Any change is wirelessly synchronized to a database server.
