What is a QR Code and Why Do You Need One?

They come to us from Japan where they are very common.
QR is short for Quick Response (they can be read quickly by a cell phone).
They are used to take a piece of information from a transitory media and put it in to your cell phone.
You may soon see QR Codes in a
- Magazine advert
- Billboard
- Web page
- T-shirts
Once it is in your cell phone,
- It may give you details about that business (allowing users to search for nearby locations)
- Provide details about the person wearing the t-shirt
- Show you a URL which you can click to see a trailer for a movie
- It may give you a coupon which you can use in a local outlet

It makes other Barcodes look outdated

The reason why they are more useful than a standard barcode is that they can store (and digitally present) much more data, including
- Url links
- Geo coordinates
- Text
The other key feature of QR Codes is that instead of requiring a chunky hand-held scanner to scan them, many modern cell phones can scan them
