What is QR codes?
There is no need to write vital details down. A simple scan captures the desired information.
QR Codes can be used to store addresses and URLs that can appear in magazines, on signs, buses, business cards or just about any product that users might need information about.

Limitation of QR codes
Users must be equipped with a camera phone and the correct reader software that can scan the image of the QR Code. Currently only Smartphone?s are technically equipped to do this. Many users that have mobile phones that have cameras are unable to get QR reading software for their phones.
