Cardinal:

from the 1970s Monty Python show concerning The Spanish Inquisition. The cardinals Fang, Biggles and Jimenez would suddenly show up in a random skit when somebody would say something like "Bloody Hell! I didn't expect The Spanish Inquisition."

They would torture the innocent with couch cushions, the dreaded dish rack, and etc. because if you were innocent "We will soon convince you otherwise."

The cardinals we are concerned with are the fraud examiners, loss prevention, audit, risk and other professionals who don't particularly like our business model. You just ain't gonna feel the love from them. They make surprise calls, conduct financial reviews, shut down accounts and generally use surprise and fear to intimidate.

As a card carrying cardinal I know how cardinals think and act which gives me a bit of an unfair advantage.

Virtualization:

Some credit cards allow you to generate one-time-like credit card numbers that can be used for transactions. It can appear to certain vendors that you are using different cards when in fact it is the same card. Sometimes used to bypass volume limits per card card transaction placed by vendors. Devastatingly effective with the US Mint credit card transaction limits and some current opportunities.
