Identification of people in the crowd by means of video surveillance cameras (scanning at a distance of a magnetic stripe, mobile phone) What are the possibilities?

Question

CCTV

Interested in a question that I could not find on the Internet. There is a need to identify a large number of people. The only resource is a video surveillance camera. I will say right away that the methods of identification by appearance are not suitable and I will ask you not to return to this solution of the issue.
Every person in the crowd has a credit card and a cell phone. What tools and software already exist to remotely read data - card number, mobile phone number, or any other data that will help identify the owner.

Answer 1

Not

Answer 2

If we are talking about legal methods, then this is a question for those to whom the Law allows it. Ministry of Internal Affairs, FSB. Perhaps someone else.
Such methods certainly exist. However, they are too resource-intensive at the moment. If I had the resources of these institutions and faced such a task, I would limit myself to monitoring a mobile phone and add video surveillance. This is from the technical side, no one cancels the usual external.
The accuracy of location determination (without the participation of any cunning applications there) can be estimated by looking at geolocation (on almost all modern phones). In the city it is very high.
