Abstract
Abstract A bar code scanning system including an optical scanner for scanning a target symbol, such as a bar code, and generating a corresponding electrical signal. The scanner housing may be mounted to a single finger ring support, which can be cylindrical in shape. The scanner housing may include a scanner activation switch, which may be of the voice recognition type. A transmitter for transmitting the analog or digitized electrical signal, either by wire or RF signal, to a receiver on the user's person is also included in the scanner housing. A decoder is preferably included within the receiver housing. The receiver housing may also have a display for displaying decoded data and a keyboard for inputting entry data. Signal processing circuitry for digitizing the electrical signals generated by the scanner may be included either in the scanner or receiver housing. The receiver housing also may include an RF transmitter for transmitting the decoded data and any entry data to a separate computer unit. The receiver housing can be worn on the user's wrist or belt.
