Well, read on. Slot players are being courted and catered to by every casino. They want you business and, in a competitive environment, are willing to pay for it by giving you the comps you deserve. To keep track of how much money their players push through their machines, casinos have opened clubs for their players. The method is simple, you sign up for these clubs at a booth the casino sets up to service club members.
Membership is free.
After you fill out a short information sheet, the casino will issue you a credit card sized plastic card with a magnetic strip on one side and your name on the other. When you play an electronic game, insert the card as indicated and your play is tracked by the casino's computer. When you play a table game, show your card to the pit boss and he will manually track your play. It is that simple. When you insert your card or play a table game the casino's computer adds points to your account according to how much money you are betting.
