</span>I haven't seen it, but I've been told that there is video of a member<br>
letting himself in with a slimjim when his RFID card didn't work. One<br>
could argue that it would have been easier for him to hack the system,<br>
but in his case I don't think so. (He's no longer around, but that's a<br>
different story. Also, the doors now have latch guards.)<br>
<br>
Anyway, this is one anecdote in favor of the idea that the people we're<br>
trying to keep out are unlikely to bother hacking the RFID system (for<br>
the same reason that burglars seldom bother to pick locks-- only nerds<br>
do that, and they're not interested in breaking in).<br>
