QR codes have a large data capacity that can store multiple paragraphs of text, website URLs, phone numbers, contact information, images, and more. Users can access this stored data by scanning the QR code with a camera phone that has a QR code reader. QR codes can be easily generated for free online using QR code generator websites and have many uses such as linking to websites, creating scavenger hunts, and more.
