Sounds like the OP did this already. Or maybe did it online or by mail.
In either case, itís probably easier and quicker to go to the credit office just to verify that itís set up and to get these questions answered.
You should also ask about the payback procedure. Some casinos will allow (insist?) you to pay it back immediately at the table if youíre ahead when you want to get up.
The fingers thing? Yeah, thatís only for well known players.
In my experience, if you apply and get approved online, you still need to go to casino services the first time to sign your John Hancock.
