A QR Code (Quick Response Code) is a two-dimensional barcode that can store various types of information and be quickly scanned by smartphones, tablets, or dedicated QR code readers. QR Codes are typically scanned by a smart phone to send someone to a specific website page.
How they work:
- Information is encoded into the pattern of black and white squares
- User points their phone camera at the code
- Phone automatically recognizes and decodes the information
- Action is taken (opens website, saves contact, etc.)
Fun fact: QR codes were invented in 1994 by a Japanese company for tracking automotive parts, but they didn't become mainstream until smartphones made scanning them effortless!
Think of them as a bridge between the physical and digital worlds - like a magic portal that takes you from a business card straight to a website with just a quick scan! ☕📱
