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.
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.
