QR codes similar to barcodes can be used for ads or promotions. QR codes offer several possibilities to marketers. If you have a traditional media advert the QR code can send the customer to a website that you can keep live and up to date, regardless of when the advert was published. The code also allows you to communicate plenty of information, without paying for more ad space, by linking the ad to the information on you own site. You can target customers more individually by giving different options when they reach the website. You can also encourage uptake of the QR code with a special promotion – customers need a reason to bother to scan the tag – and you can offer location or time based offers. QR codes are most effective in areas where people are searching for information.
