If you asked a shop keeper in today’s busy world what technology they couldn’t live without there’s a good chance that they would say it’s their barcode reader. If you are old enough to remember what it was like to check out before most shops had access to barcode technology you’ll understand why. Barcode code technology and barcode technology have not only made it easier for merchants to keep track of their inventory, they have made it faster for consumers to check out, and made the life of the stock person far easier.
The process for using barcodes is relatively straightforward. The actual barcode symbol represents a series of numbers or letters. A computer contains a database of products and each record also carries a product number that corresponds to the bar code. The magic is getting the information from the barcode symbol or sticker into the actual database that carries all the important information about the product. That’s where the barcode reader gets to really shine. The barcode reader is the tool that takes the information off of the barcode, translate it into terms the computer database understands, and then get the information into the database. Once the database is updated the merchant or supplier will have an up-to-date record that tells him or her what they want to know about the product.
It all sounds simple enough. But there is some pretty sophisticated computer brainpower that allows it to all work. Fortunately there are many very good and simple to use barcode reader systems available on the market. The average barcode reader user will not have to worry about all the heavy technical lifting. Either working with a supplier or by buying an off the shelf package you will just load your scanner and software and once the software is set up, off you go.
There are several different types of barcode readers and each works a little differently in getting the information on the barcode symbol into the computer database. The type of barcode scanner that we most often see in our day-to-day lives is the laser scanner. These barcode readers, and the pen style readers that we sometimes see, use light to measure the width of the bars that make up the barcode. This information is translated into electrical impulses that are transmitted to the computer either wirelessly or via a cable. They then go to the proper database record by reading the barcode number and the record is updated.
There are many types of technology that we take for granted in our day-to-day lives. Barcode readers are among these. The next time you are walking through a store imagine what type of logistics would be necessary for tracking inventory if barcodes did not exist. One thing is for certain, it would be far more difficult for shoppers to find what they want and to get checked out. For merchants it would mean less product, less sales, and less profits. Let’s hear it for this under recognized technology.
