In our fast-moving digital world, QR codes are everywhere. You might have seen these black-and-white patterns on products, ads, or even menus. Ever wondered what they are and how they’re changing the way we use information? Let’s dive into the world of QR codes to learn about their beginnings, how they work, and their many uses.
What Are QR Codes?
“QR” stands for “Quick Response.” A QR code is a type of barcode that was invented in 1994 by a Japanese company, Denso Wave. These codes are different from old-school barcodes because they can hold lots of info, like letters, numbers, and even symbols. They can store data up and down and side to side, which makes them really flexible.
How QR Codes Are Made
A typical QR code has black squares on a white background. You’ll see three squares in the corners and one in the middle. These help devices figure out how to read the code. The rest of the space is filled with data in a special pattern that helps make scanning quick.
Scanning QR Codes
When you scan a QR code with your phone or another device, the camera picks up the pattern. Then, it decodes the info, letting your device do things like open a webpage or show you someone’s contact details.

Need an App?
To use QR codes, you usually need an app that can scan them. These apps use your device’s camera to read the code. Nowadays, many devices come with this feature built-in, but sometimes you need to turn it on in your camera settings.
Why QR Codes Are Popular
QR codes are becoming more popular because they’re easy to use and can do a lot. Here are some ways people use QR codes:
- Contactless Payments: You can use QR codes to pay without touching anything, using apps like Apple Pay or Google Pay.
- Marketing: Companies use QR codes on posters or products to give you more info or special deals.
- Tickets: You can get your plane ticket or event ticket as a QR code, so you don’t need a paper ticket.
- Product Info: Scanning a QR code on a product can show you more about it, like how to use it or reviews from other customers.
- Health and Safety: During health crises, QR codes help with things like contact tracing or health forms.
- Learning: Schools use QR codes in books to link to extra resources or videos.
- Menus: Many restaurants now use QR codes instead of paper menus to help keep things clean.
