Here at CERN (the European Laboratory for Particle Physics) the magnetic
stripe on one's ID card can be programmed to allow access to various
experimental halls, beam tunnels, computer rooms, etc.; and  this also
allows the access computers to track how many people are in a given area 
(in case of fire, accident, etc.).  Unfortunately, high energy physicists
often work around really neat equipment that uses magnetic fields.  Some
people have a problem with needing their access card (and any credit/ATM
cards they routinely carry) replaced periodically.
