We do! QR codes are becoming more and more popular. Their typical use is directing traffic to a website. If you run a website and want people to be able to view it using their mobile devices (mainly iPhone and Android devices), add a QR code to your link and let people scan it. Most of the current “smart” phones have free (and paid) barcode or QR code scanning apps available for them. To take advantage of them you must post a QR image, like this! (It sounds like Windows Phone Series 7)
It’s actually very simple to setup, there are websites out there that have eveything you need to set one up. It takes less than a minute. We used Kaywa and their free QR-Code Generator, they allow you to set the code to link to a URL, MMS, Phone Number or Text message. Give it a shot and let us know how it goes.
