I like q r codes. QR stands for quick response. They are useful. They have been around for a while. I have seen q r codes placed onto marketing materials and even in shop front windows. The q r code means that one doesn't have to physically type in web addresses in order to gain access to said websites. In order for one to be able to scan the qr codes, the users phone should have a program on their phone which allows qr codes to be scanned. I have even placed q r codes onto my double sided business cards.
