My advice is to send high-quality, good-quality images or PDFs where every word is easy to read. Blurry pictures or cropped-off edges are the main reason documents get rejected, which just slows everything down. Licensed casinos use strong encryption to protect your data while they handle it. Once you get the approval notification, any limits on your account come off. For most people, passing KYC is a one-time hurdle. Once it’s done, your setup is finished and you can deposit and withdraw without any hold-ups. It’s the casino’s way of proving they run a safe, legal operation.
