- 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
- Web page
- 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It makes other Barcodes look outdated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
- 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
