What Are QR Codes?

QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of information. Since their invention in 1994, they've become ubiquitous in our daily lives - from restaurant menus to product packaging to event tickets.

In 2025, QR codes are more popular than ever. Let's explore everything you need to know about them!

How Do QR Codes Work?

QR codes work by encoding information in a pattern of black and white squares. When you scan a QR code with your smartphone camera, the device decodes this pattern and performs an action - like opening a website, displaying text, or adding a contact.
