I suppose this how we get a combined valuation of roughly 100 billion USD for Visa/Mastercard.
But, wait..the projected valuation of the bitcoin network is what ? 100 million today; That puts the above numbers on a slippery slope, doesn't it ?
Um that $50B was just FRAUD. VISA (and VISA only) annual transaction volume is $6 trillion (for FY 2011).
15,200 merchant banks
1.93 billion cards
78 billion transactions (~2500 avg tps, ~10K peak tps*)
$6 trillion total transaction volume (including cash advances)

* tps = transactions per second,
Yep. 50B worlwide fraud passed to merchants. Insane.
Another interesting pickle is that VISA and MasterCard are (technically) two different companies, but they clearly operate like a cartel and fix their fees together. So in other words, they are not merged because of antitrust laws, but they set the market together. They must pay a lot in lobbying fees to keep the feds of their backs.
