Scanners

Barcode scanners are elctronic devices used for reading printed barcodes. It makes lines in gorcery stores shorter, and inventories easier. It consists of a light source, lens and a light sensor that translates optical impulses into electrical ones.

There are different types of barcode readers:

PEN-TYPE READERS: - this requires the operator to swipe the pen over the code 

SEMI-AUTOMATIC HANDHELD READERS: - must position the reader near the label

FIX - MOUNT READERS FOR AUTOMATIC READING:  the reading is done by passing the label over the reader. No operator is required but the label must coincide with the reader.

READER GATES FOR AUTOMATIC SCANNING: - the position of the code must be under the gate for a short time so the scanner can sweep and capture the code targert successfully.
