Bar code scanners are designed to read imprinted bar / matrix code symbologies. Bar code scanners can be slot card scanners, fixed mount scanners, or hand-held scanners.
Bar code software identifies or decodes bar code symbology, generates output strings corresponding to barcode values, creates bar code fonts, prints bar codes, and/or performs tracking, etc.
Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.
Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment.
Wireless systems consist of combined RF components such as transmitters, receivers, transceivers, filters, down / up converters, antennas and antenna positioners.
