QR Codes – What Are They and How Do They Work?

qr+code QR Codes   What Are They and How Do They Work?

QR codes. You’ve seen them everywhere, even though you might not have even realized it. They are those black and white patterns in square boxes popping up on posters, ads, magazines and soon, almost everywhere. What are they?

What is a QR Code?
A QR code is simply a barcode that doesn’t need one of those special store scanners to be read. Anyone with a smartphone can read them, so they have become a new form of marketing. QR codes now give advertisers a way of letting you click on a link from billboards or other offline materials. The QR code, once scanned, might contain information about a company, links, images and more.

How do I use a QR code?
How do you see the information from the QR code? You need to have a smartphone with a camera. Then, you need to download a QR code reader app, of which there are many for free. The QR code reader will automatically transfer the picture of the code into a URL, contact information, phone number, etc. To find an app for your phone, just type QR into your app store search and you will have many choices.

How did I first learn about QR codes? From my son, of course. Have you already been using QR codes? Have they been useful? Which app do you use? Please share your experiences.
