How to read a QR code with your smartphone

QR codes are used for many different purposes these days, but mostly for linking to different websites. Even creating an individual code is not a problem anymore with different websites and apps nowadays. But how can you read the codes again afterwards? Here, too, you have different options.

• The easiest option is to use your cell phone camera. For some models such as the iPhone, this is also possible completely without a third-party app.
• For this, simply open your camera app and hold it over the QR code. Once this is recognized, this is displayed at the top of the screen. Tap on this notification so that you are redirected to the appropriate website.
• Alternatively, you can also use an external app. Advantage of this is that you can see directly after scanning, how the link or the data looks. Außerdem ist es bei manchen auch möglich mehrere Codes zu hinterlegen.
• Haben Sie Ihr Smartphone nicht zur Hand, können Sie auch über eine Webseite wie beispielsweise WebQR den QR-Code direkt in Ihrem Browser lesen.
• Hier müssen Sie diesen meist nur hochladen, was demnach nur möglich ist, wenn Sie eine Foto-Datei des Codes haben.
