Making Use Of A Bar Code Scanner To Keep An Eye On Inventory Quickly

By Sandra Kerr

Bar codes tends to end up on every product you purchase today at supermarkets or departmental stores. Almost everything, from the hugest fridge to a package of gum, has this distinct set of symbols that distinguishes it from all similar goods.

The distinct icons which each barcode is made up of is recognized through the height, thickness and spacing of the bars. The kind of bars used will determine the kind of information found in the code, either as numbers, alphanumeric information or character parameters.

Photo sensors in the bar code readers transfer the bars into electrical signals which can then be “read”.

The electrical signals become readable when specific software is used for converting them, and the way that the code is written is based on how tall the bars are or how spaced apart they may be.

By using a process that takes just a few seconds, the main server receives the information from the scanner software.

A decoder is the key part of the bar code scanner, depending on the model it will be able to handle 33 to 200 reads per second. The barcode reader can automatically recognize what type of code it’s scanning and deciphering.

There are many additional key bits to a barcode reader, but what are each one of these pieces for?

Look around a supermarket and you will notice a UPC symbol on almost every item. A scanner at a register reads these codes and then you are told your final amount.

Barcode scanners are also essential for a fast and easy annual inventory. By scanning products through to a computer, it is more efficient and makes miscalculations a thing of a past.

This leads to a speedy checkout when in a store or supermarket and saves customers time as well as cashiers.
