I have Players cards from most of the casino chains found in alas Vegas and MS. In my early years, I used them often, got away with it (probably because I was not very good) and after getting into OSN, have been more judicious when I use a Players Card.

Using a Players Card worked for me when I felt excessive heat or attention. The Players Card often significantly reduced heat as they tended to keep a close eye when I played anonymously, moved away to other tables when I used my Players Card. It still does at all chains except one! Maybe this chain noticed that I had been winning more than I was losing at their casinos.

in any case, on my last trip, heat increased after I handed in my Players Card. It’s almost like they have a notation by my name in their computers. As soon as they swiped my card at this chain’s casino (and it happened a few times), they gave me peculiar glances, keep coming to my table, watch me play. It was very disconcerting. I played ultra short sessions, walked away, return to another pit or table, same thing. Finally, at one casino, where I just spread 1-3 on a DD game, went down $600, slowly came back up to even, maybe up a $100 and security came up.

I got a tap on my shoulder, asked to please step away, then told that I cannot play Blackjack but was welcome to play anything else. I did not argue (maybe my quiet compliance affirmed their decision) and left.

I played at 3 different casinos of the same chain, used a Players Card, was backed away just once but received greater heat after they swiped my card. However, they did not remove me from my comped room at one of their casino.

I guess they must have some notation on their computer but only one place took action. Other casinos had no problem with my using their players card.

I have been reducing how often Zi use a Zplayers card but at that one chain, I will only use it as long as they keep my comps up.
