QR Codes: should I be using them?
If you believe, like I do, that the Internet is getting more and more mobile, I guess you should be using QR codes, as they are extremely convenient to avoid typing on your mobile mini keyboard.
[BEGIN WIKIPEDIA QUOTE] A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The “QR” is derived from “Quick Response”, as the creator intended the code to allow its contents to be decoded at high speed.
QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes. Moreover, most current Japanese mobile phones can read this code with their camera. [END WIKIPEDIA QUOTE]
URLs, phone numbers, SMS messages, tickets and more
Traditional bar codes can “store” up to 20 digits, while the QR Codes can hold up to 7089 figures in a very small space.
The most common use of them nowadays is to enconde a URL. Frame the QR code with a suitable application in your mobile phone, click and your phone will connect to the Internet and display the corresponding site.
We can also encode a phone number, a v-card (electronic business card) or a text message, that can be sent via SMS to the recipient encoded in the QR Code
Some have begun to actually begin to use the QR code as a system of ticketing for theatres, concerts, museums and even boarding passes for flights.
