Description
Hello we started seeing support from BlinkIdCombinedRecognizer for USDL and State ID.
After running multiple tests here is what I was able to scan:
USDL
Real document : Oklahoma -> OK
Photo : Delaware -> OK
Photo : Georgia --> OK
Photo : Montana -> cannot scan front
Photo : Florida --> cannot scan back
Photo : Texas --> cannot scan back
Photo : Washington --> OK
Photo : Indiana --> cannot scan back
Photo : Illinois --> cannot scan back
Photo : Maryland -> cannot scan front
Photo : Hawaii -> OK
Photo : Tennessee -> OK
Photo : Connecticut -> cannot scan back
Photo : New Hampshire -> cannot scan front
Photo : New York State -> cannot scan back
Photo : California -> OK
Photo : Minnesota -> cannot scan front
Photo : Utah -> cannot scan back
STATE ID
Photo : Arkansa -> OK
Photo : California -> OK
Photo : Hawaii -> cannot scan back
Photo : New York State -> cannot scan front
Photo : Texas -> OK
Photo : Texas (vertical) -> cannot scan back
Photo : Washington -> cannot scan back
Photo : Washington (vertical) -> cannot scan front
Environment Details
BlinkID version:
5.9.0
Device model:
Samsung S8
Device Android version:
Android Pie 9.0
Additional information
Can we please have some visibility on why not all USDL are supported.
Hi @damienlo
Thank you for waiting for our response.
Just to double-check, regarding the term 'photo', are you scanning images of real documents or images from the internet?
Are you scanning them from a monitor screen?
Also, would you mind giving us more details regarding the issues when scanning the documents?
In cases where you can not scan the front/backside of documents, do you get any certain alerts?
For instance, the "Document not supported" alert?

Hi @mparadina
regarding the term 'photo', are you scanning images of real documents or images from the internet?
By photo I kind of mean both.
For some states we have photo of real documents and for some others we simply have internet images of them
Are you scanning them from a monitor screen?
Yes
In cases where you can not scan the front/backside of documents, do you get any certain alerts?
I've been running all the test on our integrated version of blink. it's based on "BlinkId-CustomCombinedSample" project of yours.
When I say cannot scan front it means that MetadataCallbacks().setFirstSideRecognitionCallback was never called
When I say cannot scan back it means that setFirstSideRecognitionCallback was called successfully, but then onScanningDone(scanResult: RecognitionSuccessType) was not called
Let me know if you need more info or if I should run some more specific tests on my end.

Damien
Hi @damienlo
Thank you for the detailed response.
Regarding the images, I strongly recommend trying out, if possible, to test the SDK on real samples since it is trained on real documents.
The samples found on the internet can sometimes be in an invalid format or have some misplaced information when comparing it to the real document or could have some pieces of information missing.
Also, scanning from a monitor screen can also sometimes cause the scanning process for the SDK to be rather difficult when trying to extract the information from the document, since the screen can produce the Moire pattern.
When you tried to scan real documents, was the scanning process successful?
