Radio Frequency Identification, Theory and Applications

RFID is an automated data-capture technology that can be used to electronically identify, track, and store information contained on a tag. A radio frequency reader scans the tag for data and sends the information to a database, which stores the data contained on the tag. RFID technology uses wireless communication in radio frequency bands to transmit data from tags to readers. A tag can be attached to or embedded in an object to be identified, such as a product, case, or pallet. A reader scans the tag for data and sends the information to a database, which stores the data contained on the tag. The main components of an RFID system are the tag, reader, , reader.
