Is It possible to explicitly set desired document type for scan? #17

Closed bugrym closed 4 years ago

bugrym commented 4 years ago

Hi. I use this scanner for different document types and faced with problem. I have to explicitly set desired doc type for scan, because in case when I wanna scan only ID, sometimes scanner determines that it's not ID and the same happen with Passport. Do any solution exist? Thanks.

Hi, could you please clarify further what to do you mean by the scanner not determining that the document is an ID (or passport)?

So, I splitted the app flow for ID and passport. Since i can not set the desired document scan type before scan, I just check the document type which I receive in QKMRZScanResult and if it does not match previously selected option I just wanna warn user about it. During testing I found out that Scanner from time to time determines three line mrz as Passport and vice versa, two lines mrz as ID. As scanning options I just use simple enum like this: enum DocType:String { case passport = "P", idCard = "ID" }

Sorry for a delayed reply.

First of all, the user can also scan visas "V" or a driving license "D", so you should make sure your code can handle these appropriately too.

Regarding the second point, this looks rather like a bug. You should still however receive a correct document id (P/ID/V/D). Is that not the case? If so do you have any example I could test this with? Thanks

Hi. Honestly, out app just does not support visas and driving licenses. I changed a bit existing flow so this issues is no longer exist. If you want me to reproduce bug, just contact me via email: 'vlad.bugrym@gmail.com' and I will help. Thanks for you answers!
