Quick response codes are the ‘square’ – or two dimensional – bar codes you sometimes see on leaflets and posters, which hold useful information that can be scanned in on a phone, to save you manually typing it in. In those situations they might hold a URL, making it easier to visit the relevant site in your phone’s browser, or a phone number, making it easier to key in and phone it.
Kevin’s application allows you to type in small amounts of text and, by way of the QR Code Generator website (with which it communicates using Wget) turns it into a QR code that you can use in your own literature – all from the RISC OS desktop.
The latest version adds a specific shortcut for producing QR codes containing phone numbers, so that when the code is scanned on a smartphone, the phone is able to recognise that it contains a phone number, and can offer to ring it (or add it to your contacts).
If you find any of Kevin’s software useful, you could always consider rewarding him for it by buying some merchandise or with a small contribution.
