Unlocks with Your Fingerprint
If you like being on the cutting edge of technology, then the Samsung Fingerprint Digital Door Lock ($420) could be what you're looking for. This lockset is loaded with high-tech features—most notably a fingerprint scanner. In fact, it'll register and recognize up to 100 fingerprints.
You can also enable the lockset's "double authentication mode" setting, which strengthens security by requiring both a password and a fingerprint to unlock. The lock can also be operated using an RFID (radio frequency identification) card, key fob or metal backup key. It also has a built-in alarm that goes off if a burglar breaks in.
Note: The installation manual recommends keeping wet hands and water away from the lockset, so install it only on doors that have protective overhangs. It's also a full-mortise lockset, which calls for some advanced carpentry skills to install it. For more info, visit samsungdigitallife.com.
