Frequently Asked Questions
Why isn't my barcode scanning?
Barcode scanning requires a clear, well-lit view of the barcode. Here are a few tips to improve accuracy:
- Ensure the barcode is in good lighting — avoid shadows or glare on the packaging.
- Hold your camera steady and at a distance of 15–25 cm from the barcode.
- If scanning continues to fail, tap "Take a Photo" to use the AI image recognition fallback — it works even when barcodes are damaged or missing.
