There is an archive for 20-30 thousand photos.
It has a close-up photo of a credit card.
Is there any ready-made script to find such a photo?

The aspect ratio of a credit card is known. You can find the intersecting lines of a rectangle using the Hough transform and check the aspect ratio. Too small objects to skip.
This way you can filter out a large number of images that potentially do not contain credit cards.
