Sounds like you are confusing two different technologies here.
The RFID chips inside the cards are unlikely to be accurate enough to do what you suggest - both in terms of distance precision, and in terms of read success. Even if you can read within 1 centimetre and 99% of the cards accurately, that's still a lot of ambiguity and errors.
Regarding the shuffler itself, this has been the source of more interest in recent months after the Hustler Casino poker scandal around 15 months ago. Their report - wrongly - suggested that the shuffler was "secure and cannot be compromised", which is basically a red rag to a bull for the security community and they predictably ripped it apart. The talk at the Black Hat security conference demonstrated a working prototype (for a later edition of the one used as Hustler) that could a) use the camera to extract the sort order of the deck, and b) modify the algorithm used to sort the deck.
Anyone with partial or total knowledge of the deck will be at an advantage over the opponent - whether that be house versus player, or player versus player.
In the case of Pragmatic, they've got bigger problems anyway. I really should have filmed it because seeing a blackjack dealer deal from both shoes in the same hand would have been a great YouTube short
