QR or Quick Response Codes are a type of two-dimensional barcode that provide some information and can be read using smartphones and dedicated QR reading devices. Particularly, the information in the QR could be a URL of a webpage. You may have even got to this page using this QR-code

Why should you use QR?

QR allows sharing the URL through any offline media. You can place it in magazine advert, TV, at product packaging, shop displays, printed and billboard advertisements, in an email, a web page or even on someone’s t-shirt.

According to statistics, about 50% of smartphones have software to recognize the QR. This software is free. Smartphone owners long understood how convenient to get an address or other information via QR instead of typing manually.

Why should you use QR generated by copi.st?

To encrypt shorter URL requires lower resolution (dots per inch, DPI): those QR codes could be successfully scanned even from crumpled newspaper page.

The copi.st will track information about the number of times users take action to visit URL being encoded into QR, and information about the devices that scanned it.

Our QR codes are dynamic, meaning you can change the target page URL anytime after the QR Code has been printed or distributed.
