Biometric devices are a growing trend in the security market, with door locks being an obvious choice. The Samsung Push/Pull lock is a stylish and innovative design, with a unique operation where you push the door open instead of turning a handle, or pull from the inside. It allows for ten codes, twenty RF IDs, and 100 fingerprints. It can be opened with fingerprints, codes or cards, and can be programmed to require all three for an extra measure of security. Install a few and your house will look like the deck of a starship.
