You should send a private message to mikelbyl, who is the authorized representative of that poker room here on the 2+2 forums. It'll take a little while for your to get access to PMs, so please be patient.
So Mike Smith is on the right track here - these are special RFID cards, not the cards we use daily at Playground Poker Club. They are an integral part of the streaming set up, which in this case was provided by a third party, and I believe they are not a commercial brand of cards but are sold by the streaming software provider that Poker Night in America uses.
