This is the weirdest and most extreme thing I've heard in a while, I've never used a casino in my life but if we take a rough example, most banks now record your voice as a digital signature without taking a picture of your ID card, so why are casinos so extreme or are there no more sensible solutions?
The casinos that ask the customer for these strange verifications, it is clear that they want the customer to refrain from sending these documents or to fail to pass the KYC in order to issue and freeze his funds, and they are definitely scam casinos, because banks or companies now either ask the customer to send them an audio recording, passport, identity card, or driver's license, or for one of them to hold and take a selfie, or to write a paper that contains today's date, name, and the rest of the details, and holding it, and then take a selfie, but for the customer to take a selfie outside the building or street sign and showing his face while holding the government document, this is a strange thing that I have not seen before.
