Do you know that your smartphone can function as a barcode reader? Among the many things it can be used as, it can also be used to scan a QR code, also known as a Quick Response code. A QR Code is one of those alien-looking hyroglypics smudged together in a square. The squiggles it features may contain information about a store promotion, a link to a website, Wi-Fi access at your favourite cafe or even your boarding pass.

The thing is, most QR codes are in black and white. It’s kind of mundane, quiet, hard to notice… easily ignored. Get my drift? At the same time, if you’re hoping to put in your QR code into a 4C promotional leaflet or brochure, wouldn’t you prefer having it in color as well?

Now, you can — it’s possible to customize your QR code to carry colours or even your business logo on top, with the help of QR Hacker, and this tutorial will show you exactly hwo to get your first multi-colored QR code.

Generate QR Code

Before you get to customize your QR Code, you first need to go to QR Hacker’s website and start generating the code. On the left side of the screen, select the input type, insert your content and click on the ‘Generate’ button.
