This smart lock can secure your travel luggage with NFC

If keeping a suitcase secured with NFC and a smartphone instead of a key sounds interesting to you, the eGeeTouch smart luggage lock may be worth a look. Being shown off here at CES Unveiled, the lock lets you get at your luggage without a key or combination digit wheel — the ways travelers most often open a suitcase. (That's assuming you lock things down to begin with.) Instead, it uses NFC to know when you're nearby. The company says NFC is a superior solution to Bluetooth since it's proximity-based, faster at connecting, and uses a "negligible" amount of power compared to what you'd get from a Bluetooth-based smart lock.

To unlock the eGeeTouch, you can use the included NFC key tag, an Android smartphone app, or an NFC sticker for other devices like iPhones that don't let developers tap into NFC. The company claims its proprietary "Intelligent Encryption" technology can generate a unique code from over 100 million possibilities to ensure the lock won't get tricked into opening by another NFC device.
