Frame the whole code
Open Scan and allow camera access. Keep all edges of a QR code or the full width of a barcode visible, with some clear space around it. Hold steady and avoid glare. MintScan starts in All mode and reads QR, supported linear barcodes and supported 2D formats.
Use the controls inside the camera
Tap to focus, pinch to zoom, or use the zoom shortcut. Try the torch in dim light, but turn it off if a glossy label reflects it. The mode icon offers QR Code or Barcode when you want to narrow recognition. Barcode mode requests supported linear formats; All also includes Data Matrix, PDF417 and Aztec.
Review before opening
MintScan shows details before you choose an action. Copy or share a result, open a website or map, or use the relevant contact, phone, email or calendar action. Product lookup opens an online search; MintScan does not provide a product-price or stock database.
Know what works offline
The bundled recognition model decodes on-device without a connection. Creation and local history also work offline. Opening web destinations, online searches and purchases need a connection. App analytics can queue and send when connectivity returns.
If scanning fails
Clean the lens, change the angle and move back slightly. Very small, damaged or unsupported codes may not decode. Link warnings are advisory, not malware detection or a safety guarantee. Avoid opening destinations you do not trust.
