What QR codes are and do you have a QR Reader on your smartphone?

QR Codes are codes that store information like websites that most smartphones like blackberry can read.For example on BlackBerry Messenger each person has a qr code so when you are next to your friend and want to add him on BBM you can just scan his QR Code.
