This article explains potential reasons why a QR Code may not scan and offers solutions for resolving the issue.
A. QR Code Size
Ensure that your QR Code is large enough for the camera to detect its data modules. Small QR Codes are difficult to scan.
B. Wear & Tear
Physical damage can make the QR Code unreadable. Ensure it is printed clearly and intact.
C. Scanning Distance
Hold the camera at a reasonable distance, ensuring the code fits within the scanning frame.
D. Uneven Surface
QR Codes printed on curved or uneven surfaces may become distorted, affecting scannability. Always print on flat surfaces.
E. Custom Design
Designs with large logos or poor contrast reduce scannability. Decrease logo size and increase the contrast between the QR Code and background.
F. Data Encoded
Large amounts of encoded data make scanning harder. Keep data minimal for better performance.
G. Outdated Technology and Software Issues
Update your scanning device or app to the latest version to avoid compatibility issues.
H. Environmental Interference
Electromagnetic interference may hinder scanning. Avoid scanning near such sources.
I. User Error
Ensure the device is correctly positioned and the QR Code is fully visible on the screen.
