Creating QR codes is easy and free for anyone! There are plenty of sites where you can make your own QR code for free, and download/save/print it immediately:
Explore these sites and learn all the possibilities for creating QR codes. You can make a WiFi poster for your coffeeshop. A graphic for your business card that links to your FB Page. A sign that connects your clients to your online menu.
And if you just need a quick QR code for a website, just load it in Chrome. Click the Share icon at the end of the address bar, and then choose QR Code. Google will give you a QR code on the spot!
PS: once you’ve created a QR code, make sure to test it and make sure it does exactly what you want.
