What Is A QR Code?
QR codes are those mysterious black and white squares you often spot on product packaging, posters, and even online. Born in Japan in the ’90s, they were initially used for tracking car parts. But why are they everywhere now?
Imagine a barcode, but supercharged. While a standard barcode stores data in a horizontal direction, a QR code does so both horizontally and vertically. This means they can hold a lot more information, from website URLs to contact details or even a Wi-Fi password.
Scanning a QR code with a device, like a smartphone or, yes, even a laptop, decodes this data, providing a quick and efficient way to access the stored information. Hence, it’s like a portal, instantly connecting you to digital content or actions without manual input, making them a favorite tool for businesses and marketers.
