When trying to scan a specific barcode in a crowded situation in which several codes are present in the camera view, an effective solution is to exploit the user input.
This allows the user to select a specific barcode among many.
If you are looking for how to avoid unintended scanning when dealing with barcodes closed together, you can find the right article here.
To provide a straightforward experience, Scandit developed the Barcode Selection API to help the developer activate different modes to select a single code among many:
- Aim to Select allows you to select one barcode at a time using an aimer, with the possibility of tapping to confirm the selection. It is especially convenient for one-handed operation.
- Tap to select is the quicker way to select when you need to select several barcodes from the same view. Selection can be done by tapping on a live feed, or by tapping on barcodes on a frozen screen.
