Hold a barcode in visible area for detection. The window will close automatically when a barcode is detected.

The following barcode types are supported by cameras by default:

• QR Code
• Data Matrix
• Code 128
• Code 39

FAQ

My barcodes can't be recognized, but QR codes with the same content can. What's the issue?

• Quality and resolution of the camera: QR codes were designed to be well recognized even with poor image quality. Traditional barcodes may require a higher resolution or better image quality to be interpreted correctly.
• Contrast and orientation: QR codes can be read in multiple orientations, whereas barcodes usually need to be read horizontally. A slightly slanted barcode might therefore be harder to read than a slanted QR code.
• Damage or contamination: QR codes have built-in redundancy mechanisms, meaning they can still be read if part of the code is damaged or soiled. Barcodes are less error-tolerant in this regard.
• Lighting conditions: Barcodes reflect light differently than QR codes, and this could make reading difficult if lighting conditions are not ideal.
