We've been loosely following the biometric firearm scene for a couple years now, but this might well be the first time we've heard anything about password protection for your bullets. It's only a patent application as of right yet, but inventor Herbert Meyerle dreams of a day when guns have a system for firing rounds by means of a burst of electromagnetic energy, which could only be activated if a password entered into the handgun matches a password embedded in the cartridge of bullets. If that sounds a little roundabout, that's because it probably is; why fiddle with passwords -- which, once activated, wouldn't prevent your gun from being used against you before the password times out -- when biometric firearm verification makes so much more sense? As soon as you're not holding that gun, it just won't work. Or, you know, you can always hit up the swords to plowshares thing, whatever mode of gun safety does it for ya.
