QR (Quick Response) codes are those black-and-white square patterns you often see on menus, posters, tickets, and websites. Originally made in the 1990s to scan car parts, they became super popular during the COVID-19 pandemic because they allow contactless sharing of information.
Today, QR codes are everywhere—from restaurant menus to connecting to Wi-Fi, making payments, booking tickets, or verifying your identity.
How do QR codes work?
They store a small amount of data like website links, contact details, or ticket information. You can’t read them with your eyes—they must be scanned using a smartphone. The patterns in the corners of the QR code help your phone figure out the size, angle, and direction of the code to read it correctly, even if it’s slightly damaged.
How to scan a QR code:
Most smartphones can scan codes directly using the camera app. Tap it to visit the site or view the information.
You can also scan saved QR code images using tools like Google Lens (on Android) or the Live Text feature in Apple Photos (on iPhones). No need for third-party apps unless you need advanced features like saving scans or creating your own codes.
Be careful when scanning QR codes. Hackers can use them to direct you to fake websites to steal your information. Always check the link before clicking.
QR codes are fast, easy, and useful—just remember to use them wisely!
