Hi. I had a request to use in an App iOS/Android library ScandIt (https://www.scandit.com/)
If you download demo you can verify potentiality
This very powerfull and I think an use with Delphi possibile.
Do you think is possible create a component that can use it ?
I think users will be interesting. It isn't free but has high perfomance and I think interesting
But I don't it this in your target
