In relation to products used by the Casinos, these are showcased at the G2E (Global Gaming Expo -
http://www.globalgamingexpo.com/) For the use of RFID playing cards and chips, these are still the rarity, not the norm, for Casinos, (including the Caesar's chain which hosts the WSOP) so you will not find these readers on a majority of the tables, only as gimmick being tested on a few tables (normally the ones used for filming purposes).
Looking over the exhibitionists at this expo will bring up the main companies which casinos use for any of their products.
For scanning these products, they hold an extremely weak range and being an extremely rare product, is not where security threats lie, especially in relation to playing cards, where the larger faults found and exploited are printing faults, or altering cards that a player touches. Depending on the cost per deck, many countries have very strict criteria (such as Macau having to shred all cards after a fairly small time in play in contrast to Las Vegas which is allowed to recycle cards and sell them as memorabilia) we are unlikely to see this technology as a norm too quickly, since its an unneeded added cost, with Las Vegas being placed around 3-4 on the international scene for Gambling revenue, so cards are produced with Singapore and Macau casinos as the main customers.
Software wise, these come as an add-on mostly run in the Cage (cashier hubs where you cash in chips and tickets) with a link in to the security. Casinos still often have a lot of plain-clothed security and hands-on / paper tracking to back up checking people due to how reliable computers are. Normally new technology is more often used in tournaments only or at smaller venues, whilst kinks and crashing is fixed.
