QR Code Usage Tips
Choose appropriate error correction level: high level for printing, medium level for screen display
Ensure sufficient white space margin: QR codes need adequate blank area around them for successful scanning
Test scanning effectiveness: test scanning with multiple devices after generation to ensure compatibility
Optimize content length: longer content makes QR codes more complex, affecting scanning speed and success rate
Choose appropriate size: too small affects scanning, too large wastes space, choose based on usage scenario
Keep image clear: avoid blur and skew, ensure QR code edges are clear and visible
