QR Code Generator

A QR Code is a two-dimensional barcode that is readable by smartphones. It allows to encode over 4000 characters in a two dimensional barcode. QR Codes may be used to display text to the user, to open a URL, save a contact to the address book or to compose text messages. "QR Code" is a registered trademark of DENSO WAVE INCORPORATED.

What is a QR code?

QR code stands for Quick Response Code and is barcode type that was invented by Denso Wave in 1994. Get more information at Wikipedia.

Can I use the generated QR Codes for commercial purposes?

Yes, all QR codes you created with this QR generator are free and can be used for whatever you want.

Are the created qr codes expiring?

They do not expire and will work forever! QR Codes created with QRCode Monkey are static and do not stop working after a certain time. You just can’t edit the content of the QR Codes again.

A QR code is a two-dimensional code (2D code, matrix code), this means it contains data not only in one dimension (e.g. horizontally from left to right like the barcodes on the products in e.g. your grocery store) but also in a second dimension (vertical and horizontal). The acronym QR is short for “Quick Response”.

QR codes are also often called 2D barcodes. However, this notation is not correct, because it means “a two-dimensional code consisting of bars” although a QR code consists of pixels (so-called “modules”) instead of bars.

The QR code was invented by the automotive industry. Toyota asked their supplier Denso Wave to develop a barcode to safely and easily identify components. QR generators were originally used in industrial applications. Therefore, they had to be easily printable in form and size as well as staying legible when partially destroyed or dirty.

Like other codes, the QR code symbol can be captured with imaging devices like a camera and then digitally processed. A software prepares the captured image data until it can be algorithmically processed according to the QR code standard so the QR code content can be read. This process is assisted by the use of the Reed-Solomon error correction—which is also used for audio CDs to ensure that the data can still be read correctly even with small scratches on the surface.

A QR code generator is a software which stores data into a QR code (for example a text or a website address). E.g. this can be easily done with our online QR generator goQR.me: just create a QR code by typing in your data and download it as high resolution PNG or vector graphic (SVG, EPS). Now you may print your free QR code or embed it on your website to make it available to others.
