A hand-held device for
optically reading bar codes on goods, labels & shelves is Wand
A handheld optical reader
used to read typewritten fonts, printed fonts, OCR fonts and barcodes. The wand
is waved over each line of characters or codes in a single pass.
A bar code reader (or bar
code scanner) is an electronic device that can read and output printed barcodes
to a computer. Like a flatbed scanner, it consists of a light source, a lens
and a light sensor translating optical impulses into electrical ones.
Additionally, nearly all barcode readers contain decoder circuitry analyzing
the bar code's image data provided by the sensor and sending the barcode's
content to the scanner's output port.
