What is a QR Code? 


A QR Code is a specific matrix barcode (or two-dimensional code), readable by special QR barcode readers and camera phones with the right software installed. The code consists of black modules arranged in a square pattern on a white (or suitable lighter colour) background. The information encoded can be text, a website URL or other data - such as its use in our pages for automatically updating the contacts in a user's mobile phone with our contact information by sending a vCard to the device used to scan our code.


Common in Japan, where it was created by Toyota subsidiary Denso-Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. QR is the abbreviation for Quick Response, as the creator intended the code to allow its contents to be decoded at high speed.


Although initially used for tracking parts in vehicle manufacturing, QR codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (known as mobile tagging). 


QR codes storing addresses and URLs may appear in magazines, on signs, buses, business cards, consumer packaging or on just about any object about which users might need information. 


Google's mobile Android operating system supports QR codes by natively including the barcode scanner (ZXing) on some models, and the browser supports URL redirection, which allows QR Codes to send metadata to existing applications on the device. Nokia's Symbian operating system is also provided with a barcode scanner, which is able to read QR codes, while mbarcode is a QR code reader for the Maemo operating system. In the Apple iOS, a QR code reader is not natively included, but over 50 free Apps are available with reader and metadata browser URL redirection capability.

If you have a mobile phone with a camera and you can add 'Apps' to your phone then if you haven't already done so, search the relevant Application Store for 'QR Readers' or similar search terms - there are Apps that are free, probably, for your make of phone. 

When you scan the code to the right on each of our pages you will automatically update your Contacts Manager on your phone with our company name, address, telephone number and Information Department email address.
