Yeah, done that a few times, its not the most uncommon thing but not all casinos ask for it. It’s just a very secure way of proving that you are actually you. Cant really “scam” the casino with identity if you hold ID and take a photo you in it 😄. It does tho feel very silly. How long have you been fighting with them?

As said here, it is just to confirm that you are who you claim to be.
