Slot card bar code scanners are designed to read imprinted bar code cards that are passed through the aperture on the reader

Fixed mount bar code scanners are designed to manually or mechanically read items passed by their scan windows.

Hand held bar code scanners are used typically as inventory or point of sale (POS) devices.

Bar code decoders use a receiver mechanism to read a barcode and then convert the code into usable data

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

ID card readers and encoders are used to transmit personal information onto various forms of storage media and retrieve this data as needed

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
