Scanner Bin helps in a few important ways:
Avoiding significant shadows. Shadows from your hand and the smartphone or other sources cause the scanning app software to over compensate and “wash out” the lighter areas of the document.
Repeatability and ease of use. It will consistently and properly align your device to the scanned object and relieve any issues with hands shaking.
Proper lighting. The Scanner Bin allows you to either use your smartphone flash with minimal interference from other sources or you can use the LED’s (if included). The LED light is angled such that it does not create glare on the scanned image.
Contrasting background. This allows the scanning app to see the edges of the scanned object and then implement the auto-cropping feature. Auto-crop is critical for scanning lots of items in a single session.
Flattening folded paper. If you purchase a unit with the flat sheet, then it can be used to flatten receipts and letters for scanning.
