QR (Quick Response) codes are two-dimensional bar codes that are regularly used in conjunction with mobile phones to gain quick access to websites amongst other things.
How do they work?
QR codes are 2 dimensional bar codes that are used to transfer information through barcode readers that can be found on most mobile devices. Anyone with a camera phone (some may require a bar-code reader) can scan a business’s QR code and one of several things can happen:
1. They will be taken to their website.
2. They will be sent a coupon or discount.
