?? «Can you do Sumsub for a casino?» – a typical request that sounds simpler than it really is
We were approached with a task:
KYC for a casino (Winshark), verification via Sumsub.
Geo – Germany, then Netherlands, Canada, Switzerland.
At first glance – “need ID + bill”.
But an important nuance: a separate selfie was required for
each document.
? Different antifraud systems
Sumsub, Onfido, Secure – each has its own requirements for rendering, structure, MRZ, metadata and live checks.
? Geography matters
Region, address format, type of bill, dates – everything is verified as a linked system.
? Selfie stage
The document must withstand not only upload, but also a live photo with the holder – without data conflicts, lighting issues or logical inconsistencies.
We outlined geo limitations in advance, aligned the ID + proof of address format and accounted for the selfie requirement for every file.
KYC is not “any passport + any bill”.
It is a strategy tailored to a specific platform and verification flow.
