  • Magnetic radio frequency tag reader for use with a hand-held terminal
    Patent number: 5280159
    Abstract: A magnetic RF tag reader is shown for reading RF tags which transmit information to the receiver when the RF tag is disposed in a low frequency magnetic field. The reader is of a size which can be hand-held and is operatively attached to a separate hand-held terminal for receiving, processing and storing information. The hand-held terminal can be used independently for other purposes when it is not operably connected to the RF tag reader. A regular bar code reader can also be attached to the hand-held terminal means if desired.
