For example in my country it's forbidden for business to ask customer for copy of his ID, even bank's right to do so was/ is being challenged.
What's even funnier is that there are digital signature which could be used for this but I understand the cost may be the limiting factor (in my country it's over $100 per year) but I haven't seen KYC procedures accepting them.
Does your service accepts digital signatures?
We perform Tier 1 banking KYC and the most important is an AML checks to avoid bad actors on the stage. As it is an online platform, we requesting you to send us a picture where you hold your ID beside yourself, to verify that you are an existing person instead of electronic signature.
