Now that you understand what is a QR code, how can you create it in the first place? Well, you can do that in two main ways. One, use Google’s Chrome to generate the QR code of any site by sharing it in the QR code format. Alternatively, you can leverage an online generator.
Users can scan any QR code with the basic camera on their smartphone gadgets. Open the camera and move it to capture the whole code and the phone will automatically display the underneath text or redirect you to a website.
Hara Masahiro, an engineer at Denso invented this technology about 25 years ago.
Technically, you can create a QR code and make it as large as you wish. However, the standard size of a code is usually 2×2 cm.
