Event Ticketing: Attendees can scan a QR code to download tickets, access event schedules, or receive location-based directions.
Product Information: Consumers can scan a QR code on a product label to view instructions, ingredients, or reviews.

Step 1: Ensure You Have a Compatible Device

To scan QR codes, you’ll need a smartphone or tablet with a camera and an operating system (Android or iOS). Most modern devices come equipped with this capability.
