Unlock these codes..

This looks familiar to you? You can find them everywhere, on papers, magazines, advertisements, packaging, websites etc etc..

They are QR Codes, these two-dimensional codes are created in the 1990s by a Japanese man called Kaywa. His intention was to replace the traditional bar codes - those horizontal strips bar codes.

WHY QR codes?

1. allows more computation within the square patterns, hence able to store more information. (traditional bar codes store up to 20 digits, QR can store up to 7,000 characters due to the pattern!!)
2. higher reading accuracy and faster reading speed (Did I mention that QR stands for Quick Response?)
   
3. scratch resistant. You're still able to read it unlike the traditional bar codes.
4. can be read from all angles, 360 degrees
5. reduce on printing cost. Size doesn't matter here!

However, the market wasn't receptive to these codes until the late 90s. I've noticed a growing trend locally of QR codes in the recent years too especially mobile retailing.

Check out the video below how Tesco supermarkets compete with its competitors by creating a virtual supermarket via QR codes.

Awesome! Everything at your fingertips!
