What is a QR Code?
QR (Quick Response) codes are two-dimensional barcodes that store information readable by smartphones and QR scanners. Unlike traditional barcodes, QR codes can hold URLs, text, contact information, WiFi credentials, and much more. They have become essential for contactless interactions, from restaurant menus to event ticketing and marketing campaigns.
Common Uses for QR Codes
- Share website URLs in print materials and signage
- WiFi network sharing in cafes, hotels, and offices
- Contactless menu access for restaurants and bars
- Digital business cards with vCard information
- Event tickets and boarding passes
- Product packaging with instructional videos or manuals
