You know, those funny looking square-shaped pixelated designs that resemble some sort of relative of a traditional barcode.
If you’re like me, I most use QR codes when traveling by airplane. I check in to my flight online prior to departure to some destination, and I get my boarding pass electronically on my smartphone, which is a QR code.
Then at the airport terminal for my flight, the gate agent scans the QR code on my phone to admit me to board my flight.
That’s just one example of how QR codes are used. There are many more uses.
There’s an easy way to generate QR codes. Just check out barcodewire.com’s free QR code generator, you can also check out their free barcode generator as well.
