VCBC issue #7 is more groundbreaking than anything else. It was really the first time an admitted "card doctor" was interviewed and discussed what he was able to do to cards. 1996 was ages ago. The processes used now are far more difficult to detect, there are more people able to do some or all of them and those people have gotten better at it over time.
If you are not a know it all and want to be more current with what can be done to cards you really need to spend time on Kevin Saucier's site.

VCBC issue #7 is not the end of the education one can acquire on this matter-- it is merely the jumping off point.
