RFID goes UHF
Standards, regulation, pitfalls
Radio frequency identification (commonly known as RFID) is a generic term used to describe a system that transmits the identity (in the form of a unique serial number and data) of an object or person wirelessly, using radio waves. These wireless systems allow for non-contact reading and are effective in manufacturing and other hostile environments where traditional identification technologies such as bar code labels could not survive. Having its radio origins in LF and HF bands like 135 kHz and 13.56 MHz, RFID is now rolled out to UHF, too.
