What is a QR Code?
A QR Code is a 2D (two-dimensional) barcode image that resembles a square-like maze, that is readable by QR barcode readers, smartphones, computers and webcams. The QR code has been around for many years and started in Japan in 1994 by denso-wave a subsidary of Toyota.
Over the last couple of years QR codes have started to gain huge popularity in the UK, US and Europe with the use of smartphones being able to read the QR Codes with a QR Code Reader.
How does it Work?
A 2D barcode (QR) can store up to 7089 numbers, as opposed to a traditional 1D barcode (UPC/EAN) which can only store up to 30 numbers. This additional storage capacity allows further data beyond numbers to be stored. This data includes hyperlinks, SMS/MMS messages, text, contact entry and calendar entry etc. The ability to store a hyperlink makes many things possible, such as playing a video, updating a Twitter status, ‘liking’ a Facebook page, displaying map directions, and much more.
Decoding a QR Code
a QR Code requires a 2d barcode reader app to encode the data and display the information to the user.
