In today’s digital world, QR codes are more than just black-and-white squares — they’re a powerful bridge between the physical and digital worlds. From scanning a restaurant menu to paying bills or accessing product info, QR codes are everywhere.
But what is a QR code, and why has it become one of the most essential tools for modern communication and marketing? Let’s explore.
What Is a QR Code?
A QR code (Quick Response code) is a type of two-dimensional barcode that stores data such as text, URLs, contact information, or payment details. It can be scanned using a smartphone or QR code reader, instantly connecting the user to the stored information.
QR codes can store over 100 times more information than traditional barcodes, making them ideal for modern use cases across multiple industries.
How Does a QR Code Work?
When you scan a QR code with your smartphone camera or a dedicated scanner, the code is decoded and converted into readable data. This could open a website, show a message, launch an app, or even trigger a payment.
Most modern smartphones come with built-in QR code scanners, making access instant and user-friendly.
