To read about 152-FZ "On personal data"

Can collect data with user consent.
The question is:
Why do you need passport details then? I can't even remember where I found them in the Internet needed, except for state services and banks.
Verification enough for phones or soap. Well, or by credit card if you are all on the online payment. Doing a test payment to an unknown number of rubles if the payment went through, then the person is the cardholder
Sergey, maybe you know - are there any requirements for the storage of user data (scans of passports, the text data)? May need to require encryption or something? - Dorian.Dic commented on June 8th 19 at 17:21
