A QR Code which stands for “Quick Response Code” is a mobile phone readable barcode, in its simplest sense think “print based hypertext link” – we can encode your web address / personal message / telephone number into the QR Code and then you just point a mobile phone which has QR Code decoding software installed on it and it will allow the user to visit the site, read the message or phone the number. More and more phones are coming with QR Code reading software already installed on them.

The technical specifications for a QR Code are set down in the ISO-18004 standard so they are the same all over the world, and the only significant variations from one QR code to another (apart from the data it contains) is the number of modules required to store the data. A Version 1 QR Code is a 21×21 array of data elements with the array increasing in size by 4 modules for each increase in version number. The largest standard QR Code is a Version 40 symbol that 177×177 modules in size and can hold up 4296 characters of alphanumeric data (theoretically) compared to 25 characters for a Version 1 QR Code.

To make things a bit more robust, the QR Code also contains its own error correction data, internal orientation calibration and self-alignment markers. In this way it doesn’t matter whether the QR code is upside down or wrapped around a curved surface, the message will still get through.
