	As I recall, the mag-stripe on a _real_ BART ticket has a
substantially higher Curie temperature than grut mag-tape. The hack
involved using a stripe of 1/4" reel-to-reel tape, which was glued to
an old ticket (or piece of paper) _after_ being "ironed". These hacks
are quite detectable by _sight_, if the station agent happens to be
suspicious. There may have been folks who managed to "iron" directly from
one ticket to another, but I never heard of any.

	Note also that the iron technique would tend to produce "spread-out"
patterns which may get "corrected" by the fare-gate reader, but could
still show up on the more complex widget the station-agent uses to, for
example, verify damaged tickets.

	Even if the counterfeiters had substantially higher-tech gear than
the average hacker, it is hard to make money faking something worth $20
max, unless you _sell_ it. It is quite possible the arrests were made
as a result of "normal police procedure", e.g. following up on street-talk.

	Of course, _I_ never had anything to do with this stuff and don't
know anybody who did.
