Be ready to prove who you are. Golisimo will likely ask you for identification to confirm your identity, age, and payment method. This routine security check, known as KYC (Know Your Customer), serves to prevent fraud. You’ll have to submit clear copies of items such as a driver’s license, a recent bill, or a bank statement. If you don’t complete this verification, the casino may block your account and lock any money in it until it is done.
