As far as certification card recognition goes, I think that those days are way behind us. Thanks to blackberries, cell phone internet access, laptops and the rest, there is likely to be no problem whatsoever with certification cards especially among the RSTC, WRSTC and Universal Referral Program members. Certification cards have been inappropriately used as weapons in the past by dive center staff and owners to strong arm taking training at their facilities. PADI's only real hold on the diving market is that theirs is the world's most "recognized" card. They like to make people think that "recognized" is the same thing as "accepted" but that isn't true. If a PADI facility refused to accept a PDIC certification, the PDIC diver merely needs to call or email PDIC and that diver will be speaking directly to one of the presidents and not just an office employee. In no time, PDIC HQ would contact PADI HQ and heads would roll.
If one equates dive training agencies to organized crime, ACUC, BSAC, CMAS, IDEA, NAUI, SDI, SSI, PADI, PDIC and YMCA are all crime families. PADI's tactics in the past by creating fear in the resort and dive travel industries caused IDEA, NASDS, NAUI, PDIC, SSI and YMCA to cooperate by forming the Universal Referral Program. SSI took over NASDS so now the major crime families out of North America are ACUC, IDEA, NAUI, SSI, PADI, PDIC, YMCA along with SDI. PADI doesn't like to play well with others and wants to dominate the world, much like the US government, and like the government hides behind a great propoganda campaign. NAUI, PDIC, SSI, IDEA and the YMCA are like the Italian mafia - a few families trying to make money the old-fashioned way (teaching quality diving). They pretty much want to control the world too, but want to do it over spaghetti marinara and a loose cooperation. SDI wants to get in on the fun. They're like "new money" and they joined our exclusive club. The Universal Referral Program agencies are aligned against PADI more so than each other. They try to tread lightly when stepping on each other's toes, but when encountering PADI they take great joy in "sticking it to the man".
Agencies like NSS-CDS, NACD, IANTD, TDI and GUE are fighting a different war. They'd be like the Middle East. The cave diving certs predated open water certs so it's like they've been around forever and just want to be the only ones left standing on their patch of land. GUE is like Israel. They believe they are God's chosen people and moved into this land late enough to really piss off certain factions who just want them killed.
Other agencies are like other crime familes and criminals. They're real, they're out there and they want a piece of the action.
Becoming an instructor trainer for me means that I can really fight back against PADI by pirating THE GOOD and EXPERIENCED instructors from them & turning them loose to wreak havoc and produce the best divers they can... now where did I put that Black Pearl?
C-cards are just supposed to say that someone has been trained at a certain level and asking to see a C-card protects you from gross negligence in not having checked to see if someone is certified for a level when filling tanks of oxygen, air or mixes for diving. If a guy showed me a Croatian Sub Sea Trimix Training card, I'd fill his tanks, but I'd do my best to verify the card was real & then just photo copy and file it if I suspected it wasn't a valid organization. Besides, the industry polices itself over all and in many countries one doesn't need to be certified to dive. I think the only people I've ever met who were concerned about what agency was on a card were PADI facilities in the past & recently never heard of any problems.
Centers are too poor to care.

Peter,
From what I've seen as long as the operator(charter,dive center ect) sees a card they'll take your money.To the best of my knowlage there is no law that requires someone to have a cert card to dive,buy or rent gear.
They want the card to fill out the paper work to keep their insurance provider happy.
