KYC (Know Your Customer) is the set of procedures for verifying player identity. In regulated markets it is a legal obligation; in practice it is also the main friction point of the signup funnel.
Every KYC flow is a negotiation between risk and conversion. The mistake is not picking a side, it is failing to measure the cost of the side you picked.
Where the funnel usually breaks: document capture on mobile (framing, glare, camera quality), liveness checks, registration data inconsistency and, above all, a manual queue with no SLA, which is abandonment disguised as review.
Worth measuring: automatic approval rate, abandonment per step rather than only in total, median time to approval, rejection rate overturned in manual review, and cost per approved verification, different from the per-query price charged by the vendor.
Whatever the design, it must be written, dated and logged: in an audit, what you demonstrate is the criterion and the consistency of its application.
