What is a QR Code

When Restaurant Café Olai Helsingør opened under Corona restrictions, a QR code was introduced to read the digital and contactless menu card

QR Code is a two-dimensional "bar" code - also a so-called matrix code, which was developed in 1994 by the Japanese company Denso-Wave. "QR" is a synonym for quick response, which is the idea behind QR codes.

The QR code is "free", In return, the developer demands that the company be accredited with the text "QR code is trademarked by Denso Wave, inc."

The idea behind the QR barcodes was that they should be used in the production of cars, where robots etc. could automatically recognize the QR code.

Gradually, QR barcodes have been widely used in general and are used today for a wide range of purposes because the QR code can contain much more information and larger blocks of text and can be quickly read by a mobile phone such as: Postal addresses, URLs to web pages, phone numbers, email addresses and countless other places.

When you insert and use the QR barcode, it is saved as an "image file". JPEG

You must be aware that a QR barcode can contain very large amounts of data, and is therefore often used by hackers where tracking cookies are inserted without your knowledge, this often applies when you use the "FREE" offers on Google
