Subject QR-codes:

A QR code (short for: Quick Response) is a good way to pack and share a lot of information.

The QR-Code consists of square white and black dots representing the binary data. The three corners of a QR code are used as orientation and indicate where up and down are. The usage of a QR code is free of license.

To read QR codes you need a camera with a connection to the internet and an appropriate software for reading the code. Usually you get a suitable app for almost every smartphone in your app store. Just search for "QR scanner".

A dynamic QR code, (usually shorter) URL will be generated for the target URL on the QR.net server. If the QR code is scanned, the URL is technically called first on the QR server and then the user is forwarded to the actual destination URL. This is the only way the call of the QR code can be recorded and evaluated in a statistic.

Your QR-Code can easily be printed with most printing methods. Make sure that the contrast from the background to your QR-Code is as high as possible so that the code is easy to recognized. Should this not be the case there may be problems during the scan. You can also color the generated QR code by using a graphics program, but make sure that the code color stands out from the background color.

At the size of a QR code there are no limits as long as the reader can analyze the whole picture. But consider that you can badly scan a whole poster with a smartphone if you stand directly in the front of it.

If you have decided how and where you want to print and spread your code, note the focus of the print. Especially in textiles you should possibly customize a test print and test this with your smartphone. QR codes can be printed for example on:

Subject premium membership:

As premium member you can generate dynamic QR codes up to 1,000. Additionally, you can custom individual short URLs for your QR code in the format https://qr.net/yourKeyword. You also obtain other functions such as API access.

The premium membership costs €99.00 per year (including VAT). You can easily and automatically pay via Paypal and will be released immediately after successful payment for 1 year. You have no notice period and commitment period: Your membership expires after one year automatically unless you prolong not running for another year.

With the API, you can create QR codes automatically as premium member. Your server queries to our server API and gets returned as a response to the QR code. This makes sense when you generate automatically regular new QR codes.
