You probably scan them all the time, but what about making your own QR codes? You can embed text, links, and even passwords.

These square codes are quick and easy to use, and since Android and iOS users can scan QR codes with their phone’s default camera, people don’t need any special software or update to make use of your code. On top of that, QR codes require no physical contact for you to interact with them, so it’s not surprising that they’re now taking off.If you’ve ever wanted to make your own QR codes, know that it doesn’t require any great degree of technical know-how or a huge amount of time.

But these patterns can do even more than that. You can encode your contact details in a QR code, for example, and print it on your business card. That way, every time someone scans it, all of the details you’ve shared will pop up in their default contacts app, ready to be saved. If you’re running a live gig venue, you could have a QR code printed on the bottom of posters advertising future shows, which will take people directly to the website where they can buy tickets.

On a more simple level, you might want to create a QR code that includes login details for the Wi-Fi network in your home or Airbnb rental. Guests could scan the code on entry, which would connect them up to the wireless internet without any need to search for a network name or input a password.It only takes a minute to generate QR codes for these simple uses. There are more advanced ways to use these patterns, like logging directly into websites or apps, for example.
