What is a Barcode Scanner?
A Barcode Scanner also
popularly known as the price scanner or a point of scale scanner is
basically a stationer or handheld device which is used to capture as
well as read the information that is contained in a barcode. A
Barcode reader will have a Barcode Scanner, a built-in or an external
decoder along with a cable. The cable will be used suitably to
connect the Bar Code reader with a computer. The Barcode Scanner dealers in Kolkata
supply Barcode scanners which will capture as well as translate the
barcodes into letters or numbers. This data will be subjected to a
software application which can decipher the data and make use of it.
How does the Barcode Scanner work?
The Barcode scanners supplied
by the EAS System
dealers in Kolkata
will be connected to a computer by means of a serial port or a
keyboard port or through an interface which is known as a wedge. A
beam of light is directed by the Barcode scanner which falls on the
barcode. The amount of light which is reflected is measured. The
light energy will be converted to electrical energy by the Barcode
Scanners supplied by the Barcode
Scanner dealers in Kolkata. The electrical energy thus generated is further converted into data
by the decoder. This data is then forwarded to a computer for doing
further necessary work.
