What are QR Codes?

Quick Response (QR) codes are matrix barcodes designed for fast readability and high data storage capacity. Initially created in 1994 by Denso Wave to track automotive parts, QR codes have evolved to become a ubiquitous element in marketing, retail, healthcare, and beyond. By encoding data in a compact square grid, QR codes can store URLs, contact information, Wi-Fi credentials, event details, and more.
