A lot of people tend to make a barcode seem more complicated than it actually is. I've always considered that a barcode is a string of characters that are machine readable.
The most common barcodes, and the type that we all see when we do our shopping (remind me to tell you about my retail therapy course some time ;-) ) is known technically as linear or 1D codes typically representing up to 20 characters per code. Whilst there is no reason why a linear barcode should not encode more characters than this, I am told by my technical colleagues at Datalinx, that more than this and the size of the printable code starts to becomes too big or the thinness of the lines within the code becomes too small.
Having been around for a few years (a lady never tells you her age) and not living in a cave. I have to admit that barcodes are everywhere and not just on the food you buy in the supermarket (although that’s the place you usually notice them).
Putting a barcode on an item means it can easily be tracked and counted. Usually this is part of an automation process. The automation bit ensures that the data from the barcode is captured quickly and accurately allowing a business to be more efficient.
Wireless Scanning and scanners should not be confused with a wireless network, there is a subtle difference between the two.
Ok, so when you work with wireless scanners you provide your warehouse team with more flexibility. They can collate and/or pack orders as they are moving around the warehouse, which speeds up the dispatch process and they won't need to connect the handheld to the computer to transfer the data from the transactions they have just completed to your software package.
When it comes to receiving stock into your stores your team can scan the barcode location (bin) as the product is put into it. Giving you accurate (and true) information which you wouldn't necessarily get if the handheld couldn't be taken around the warehouse and you were assuming the product ended up in the correct location.
The alternative is to use fixed position scanners....

The World Health Organization (WHO) estimates that up to 1% of medicines available in the developed world are likely to be counterfeit and when applied globally this figure increases to 10%. With many of the medicines used in the UK manufactured overseas, this multi billion pound marketplace is attractive to those who would exploit and sell dangerous and counterfeit products into the supply chain.
