Zcore on WOV who is a Casino Staff Member said that he and his Team knows when Players pull Player's Club cards when Bonuses hit. A Poster said something like, "My Friend who lives in a different State visited me one weekend and he and I went to my local Casino. He had a Promo for first time sign up, earn 50 points and get $200 in free play.
He earned the 50 points and got the $200. We were leaving the Casino in a few minutes because he was going to catch a plane back to his State soon. He told me I could keep his Player's Club card and play the $200, just Zelle him his half of whatever I lost." I agreed and kept his card.
The next day, I played with his Player's Club card and got the Bonus. I pulled his Player's Club card out of the machine and put my own card in. I ended up hitting a HUGE Jackpot with my Friend's free play money but my card was in the machine when the Slot Technician came to verify my win and I claimed the Jackpot using my own Player's Club card and ID.
I Zelled my Friend $2,500 out of the $5,000 bonus. There is no way that the Casino will find out that I won the Bonus using my Friend's free play but just switched the cards when the Bonus started."
Zcore responded something like,"I am a Casino Staff Member and my Team and I know when Players pull out Player's Club cards when Bonuses start. You and your Friend MIGHT get away scot free since your Player's Club card was the one in the machine when the Slot Technician verified the win and the Casino thinks you pulled out your own Player's Club card impulsively and put it right back after using your better judgement, but you'll be pretty much screwed if they check the cameras and see that the Player's Club card you initially put in and were playing on was not your own Player's Club card and you pulled your Friend's Player's Club card out in your own Player's Club card when the Bonus started."
