With the AI Card Detector you can scan your playing cards with artificial intelligence in your iPhone. The Image Classifier is trained with over 1000 playing cards. The best precision you can have is if you put the card 5 inches before the camera lens.
This app helps visual impaired people to play cards with an easy way again.
The process is very simple.

-> Plug a headphone in one ear
-> take a small table mount for your phone
-> Start the app
-> put the card under the camera lense
-> And Siri tell you which playing card it is

Supported is now the small collection for cards to play Poker, Black Jack and so on.
This App is not finally and in training to be better. But this precision is at this point very nice.
