Where to buy Barcode Scanners?

As a kid I was always very interested in the barcode scanners at the Supermarket. I wondered how the laser beam worked and how they didn't cut the packaging in half!

As an adult I know that the humble barcode scanner is not that mystical anymore! However there still are some mysteries as a business owner such as where do you buy a barcode scanner?

Well there are a lot of companies. One company is called PoseGuys.com, no idea why they have the name but they sell the scanners and the computers to process and organise the info and print the receipts too.

Thanks.
