With the help of the QR-code, it is possible for you to load the address and contact information of Messe Düsseldorf GmbH directly into your mobile phone and save it under contacts. All you need is a smart-phone (eg iPhone or any other similar device) and the software needed to read. For the iPhone we recommend: i-nigma. Download this software free of charge in the App Store.
QR Code - What is it?
The QR code is a square matrix of black and white dots, representing the binary encoded data. A specific mark in three of the four corners of the square provides its orientation. The data in the QR code are protected by an error-correcting code.
How do I use QR code?
After installing i-nigna on your iPhone (or similar devices), start the software. You will see a camera cut. Hold your iPhone above the screen that you can see the full square with the iPhone camera. It is captured automatically and translated into the clear text.
