In highschool, I had an ongoing fear that one morning I would just entirely forget the combination to my locker. It never happened, but the iFingerlock Personal High Security Padlock would have certainly saved me some anxiety. This tactical biometric lock works off of your finger print to unlock whatever high security item you have behind the lock. You can even give access to friends/family as it accepts 10 different programmed finger prints. I guess the only thing you need to worry about is the 2 AAA batteries dying… but we’ll worry about that later!

The iFingerLock sells for $75 from Amazon.
