that's so dumb to assume credit-cards are of any use in avoiding a bust. they issue a card along with skeleton personal history to almost every badge in "deep" cover(meaning they don't go back to their other identity when the workday ends).

so basically, the guy you're trying to identify is going to check out fine. if all they're doing is a quick background check or stuff with a mailing addy, you wouldn't even need to be that undercover at all to get through their screening.

the whole idea is just retarded-it's no safer than taking cash unless you're planning real surveilance on them and that's one of the businesses that's perfect for cash-only. once money's on record, it's a bitch to clean. you can have the shadiest account set up in gibraltar, but if you're planning of living in the states you've got to get the money there and figure out how to explain what the fuck you were doing with it when you inevitably get pinched because of it. that's why guys who have 30-year careers like eddie w. have 2 million in suitcases
