NFC (Near Field Communications) technology is becoming more popular, Google recently launched their new NFC based payment system, Google Wallet, and now it would appear that Yale, the company well known for making door locks, intends to use NFC technology in future door locks.
Yale has showcased an NFC-enabled door lock at the CEDIA Expo 2011, and the door can be locked and unlocked by holding your smartphone up to the door.
How NFC Technology Works
NFC technology allows devices to communicate with each other when they are in close proximity, typically within a few centimeters. This is achieved through electromagnetic radio fields. The technology is widely used in contactless payment systems, such as Google Wallet, where users can make payments by simply tapping their smartphones on a compatible terminal. The same principle is applied to Yale’s NFC-enabled door locks. By holding your smartphone near the lock, the NFC chip in your phone communicates with the lock, sending a signal to either lock or unlock the door.
According to Yale, the technology is very simple and no back-end system is needed, just the lock and your smartphone. This simplicity could make NFC-enabled locks a popular choice for homeowners looking for a convenient and secure way to manage access to their homes. The absence of a back-end system also means that there are fewer points of failure, potentially making the system more reliable.
Potential Applications and Future Prospects
The introduction of NFC technology into home security systems opens up a plethora of possibilities. For instance, homeowners could grant temporary access to guests or service providers by sending a digital key to their smartphones. This could be particularly useful for Airbnb hosts or for allowing access to cleaners and maintenance workers without the need for physical keys.
Moreover, NFC technology could be integrated with other smart home systems. Imagine a scenario where unlocking your door with your smartphone also triggers your smart lights to turn on, your thermostat to adjust to your preferred temperature, and your favorite music to start playing. The possibilities are endless and could significantly enhance the convenience and functionality of smart homes.
However, as with any technology, there are potential drawbacks and concerns. One of the primary concerns is security. While NFC technology is generally considered secure, it is not entirely immune to hacking. Cybersecurity measures would need to be robust to prevent unauthorized access. Additionally, there is the issue of what happens if your smartphone battery dies or if you lose your phone. Backup access methods, such as a traditional key or a keypad, would likely still be necessary.
We wonder how long it will be before we see this technology in our homes. Given the rapid pace of technological advancement and the increasing popularity of smart home devices, it may not be long before NFC-enabled locks become a common feature in households around the world.
