Scanning SA ID Card and License Card using barcode scanner

[Sindile]

Thank you for your response and suggestions.

@LN

First, I want to confirm that you’re using Collect v2025.3.x because prior versions used a different library for barcode scanning.

I am using Collect v2025.3.1

The most reliable way I’ve found to scan the bottom code is to put my finger on the upper barcode to block it from being read. When I do that, even just on a bit of the upper code, the bottom code is scanned quickly and reliably. Could you suggest that process in the form?

I have tested this suggestion it does work (will use that for now), it would be nice to have this option maybe in future with resources permitting. I note Dynamsoft Barcode Scanner has settings to select the type of barcode format.

The driver’s license has an extremely dense PDF 147 code. It’s probably possible to read with a very high quality camera that is perfectly still in perfect lighting conditions but unfortunately that’s going to be hard to do reliably. In the past, we’ve seen projects make very simple rigs out of cardboard to hold a phone at an optimal focal distance. Have you experimented with a real physical card? The image provided has some resolution loss already.

Even with a physical card I am unable to read the barcode (I also agree that it is encrypted). I then tried with Dynamsoft Barcode Scanner on the attached Drivers License and it was able to read and decode the barcode when selecting US Driver’s License and not with General Scan.

I will continue investigating - maybe find a third party app that I can open from Collect to read the barcode and get the decoded information - not sure if this is possible.

Thank you.
