I don't know if this is such a good idea.  It seems to involve more risk
then benifits.  As was pointed out, such things can be unhealthy for
pacemakers, disks, bank cards, etc...  Someone else menthioned the
security systems used in stores, libraries (our campus uses them) that
involve having the books, mechandise tagged w/a small foil strip.
The sensing mech. seems to produce noise on walkmans but doesn't
harm diskettes, cassette tapes, etc. (although at the library, they
have a notice warning not to take mag. media through & I have had
a person I know have a floppy disk zapped)  My Sony D-10 CD player
seems to set these systems off if it's on.  Even using this system
may be impractical to get into a managable size.
