We know the Near Field Communications (NFC) technology is used to replace the credit card by your smartphone. But, for sure, this technology might have more applications. As example, we can see the first NFC-enabled door lock presented by Yale Locks & Hardware. To open it just put the smartphone near the lock and if it accepts the electronic key you’re in. Simple and the same time secure. You don’t need any connect except NFC, of course.
Additionally the new Yale door lock sports touchscreen to type unlock code manually and it’ll supports Z-Wave or ZigBee to integrate the lock into the home automation system. You may see the sort demo video after break.
