I went to my local casino last night (Gentings in Southend) and they had a new card - the one in black on the left. I figure it was pretty new as when I sat at the table and handed it to the dealer, neither he nor the pit boss had seen one before! I also picked up one of the cards on the right which I assume must have been the previous issue, but was different to the previous one that I had - so they have used 3 designs at least in the past few months!

I have one of the black cards for trade (possible sale?) if anyone has any UK cards, or maybe a Paris LV LE (I'm trying to get them all having picked up a few when I last stayed there). The card has "Cash 23" written on the signature strip as they issue them to people who don't have a card but who want to play the slots.

Enjoy
