RFID Tags vs QR Codes: Features, Differences, and Use Cases

What are QR Codes and how are they used? QR Codes are two-dimensional barcodes that store data in a square grid of pixels. They act as a bridge between physical objects and digital information. Because they store data both vertically and horizontally, they hold much more information than a standard barcode. Digital sensors, like those in a qr code scanner, locate markers in the corners to decode the pattern. QR Codes use cases include: Marketing: Linking flyers to website URLs or videos. Hospitality: Providing digital menus at restaurant tables. Payments: Enabling quick transfers through apps like UPI. Connectivity: Sharing WiFi passwords without manual typing.
