COST $99 ($179 for two, $350 four-pack)

AVAILABLE FROM tapplock.com

WHAT'S HOT The lock stores up to 500 fingerprints, so family, friends or neighbors have access without the need to place a key under a rock or text a combination code.

With the accompanying Tapplock app, you can track who unlocked the padlock and when it happened. The app allows you to grant mobile access with the remote unlock feature via Bluetooth. A third unlocking method is with Morse code, by pressing long and short combinations on the power button. The app can be set to limit users' access to specific dates and times. Access can also be removed at any time.

The padlock can withstand the elements in almost any weather situation. This includes being completely submerged in water, so rain will not be an issue. According to Tapplock testing, it's fully functional between minus 4 and 149 degrees along with being dust- and rustproof.

There's an internal battery that should last up to a year on a single charge and up to 3,500 unlocks per charge (USB). The lock has a blinking red light when it goes below 10 percent of power remaining; the Tapplock app shows the power level.

Inside the lock is 128-bit encryption with myriad security protocols for enhanced protection.

The Tapplock is available in sterling silver, gun metal and midnight black.

WHAT'S NOT There's been no third-party security testing and certification.
