• What is a QR Code?

  A QR (Quick Response) code is a type of two-dimensional barcode that can be read by smartphones and dedicated QR readers. Unlike traditional barcodes that only store numbers, QR codes can hold URLs, text, contact information, Wi‑Fi credentials, and more. Businesses use QR codes in advertising, product packaging, event ticketing, and logistics because they connect the physical world to digital content instantly. Consumers scan them with their phone camera to open websites, download apps, or view menus without typing long URLs.

  QR codes were designed for fast scanning: the pattern stores data redundantly so minor damage or low resolution still often works. MayQR helps you keep codes visually striking while preserving the structure scanners need.
