What is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that contains information such as text, URLs, email addresses, phone numbers, or even geographic coordinates. It’s a simple yet powerful tool used for instant data transmission between a reader device and a digital device.

QR codes were invented in 1994 by Masahiro Hara of Denso Wave, a Japanese automotive components manufacturer. Initially designed to track parts during manufacturing processes, QR codes have evolved into an essential tool for various industries and applications.

Product Information: Share detailed product information, such as instructions, ingredients, or reviews.
Food and Beverage: Provide nutrition facts, recipe suggestions, or even mobile payment links.
Travel and Tourism: Display maps, itineraries, or special offers to travelers.

Healthcare: Share medical information, appointment reminders, or patient education materials.
