QR codes are seen everywhere these days, from labels and product packaging to business cards, banners, and postcards. With around 89 million Americans using them for mobile payments, information access, and promotions, it’s no surprise that global QR code usage has increased by 57% in 2024. In fact, their visibility is expected to rise by 22% in 2025.

The QR codes we often see are small, pixelated boxes and you might have, at some point, thought if they always had to be square.
QR codes , or quick-response codes, are two-dimensional barcodes composed of data modules in a specific shape, usually a square. These modules can store encoded data like URLs, payment information, or contact details. Unlike traditional barcodes that are read per line with a laser scanner, QR codes can be scanned simultaneously using a smartphone.
QR codes were originally designed as squares when they were invented in 1994 by Masahiro Hara, an engineer who worked for Denso Wave. While it may seem like a coincidence, there are several reasons why QR codes are designed to be square:
