QR Codes

New year's coming soon so Happy New Year(: Today I'm telling you about QR codes;

# What's a QR (quick response) code?

This is a square module with bars and points on its area and a framed square in each corner but in the right bottom corner. It encodes stored information you can access rapidly.

# How is it used?

When you catch a code with an app in technological gadgets with its camera, it searches the information on it and shows you (as a link, message...), in a quickly way.

# What's its storage capacity?

They can storage as maximum 1,817 characters from the Japanese Alphabet Kanji/Kana; 4,298 alphanumeric characters; 7,089 numeric characters or 2,953 MByte as bynary or data. They have between 7% and 30% of error correction.

# What's its origin?

Denso Wave (Toyota) created these codes on 1994 to register and manage their spare parts for vehicles in a high speed. Later, with mobile phones they got common, specially in Japan.


I hope it was useful and I wish you a happy new year's eve and a better year than 2013, because 2014 has to be great. Kisses and hugs to everyone <3 See you.
