Best NFC Smart Locks

Currently, it is very difficult to find NFC smart locks sold by any major retailers in the US. Whilst manufacturers such as Yale and Neatmo tried to introduce these locks to the market, they have still not been able to roll them out for various reasons.

The NFC Rings brand in the UK does have a model which sells out pretty quickly. In the EU, you might also find a few on ShopNFC based in Italy. Another place you can find smart NFC locks is Alibaba, however, we’re not 100% on how secure they are—Caveat emptor!

Best RFID Smart Locks

Samsung is the most reputable supplier of RFID locks although there are a number of smaller manufacturers also competing in this space.

Unlike NFC door locks, RFID door locks use electromagnetic fields to automatically identify and track tags attached to objects. RFID locks feature a tiny radio transponder, radio receiver, and transmitter.

Benefits of NFC & RFID Door Locks

Access Control & Monitoring

The advantage of NFC and RFID locks is they allow for easy access and control. Typically, these locks thrive in short-range operation much like Bluetooth technology. You can decide who comes in and who doesn’t.

Additionally, these locks can be wirelessly connected for real-time tracking and communication. Furthermore, the NFC locks and RFID chip locks require a very little source of power which allows them to operate for months without having to replace batteries.

Ease of Use

Furthermore, NFC and RFID locks are extremely easy to use. For one, they offer an easy authentication process which, in turn, improves their efficiency.

Typically, on average, the locks take between 0.5 and 2 seconds for authentication. Plus, using some of the best RFID and NFC door locks, you don’t have to worry about remembering codes or using keys.

Wireless

You can also find wireless options without having to connect wires around your property. Through this connection, you can then control the door lock using access cards or smartphones via the NFC chip. Some wireless door locks are even compatible with smart home systems.

Home or Business Use

NFC and RFID door locks are also designed to be used in both homes or offices. These locks are available in a cross section of designs to suit homes, apartments, hotels, and airbnbs, just to mention a few.

For example, the Nyboer Keyless Door Handle can be programmed to be used with over 200 different RFID cards or 200 fingerprints, making it perfect for office settings.

Questions on NFC and RFID Locks

What is the difference between NFC and RFID?

The main difference between NFC and RFID technology is that NFC is a subgroup of RFID technology. Generally, RFID is identified using radio waves with three main tools—a tag, reader, and antenna. RFID devices come in a passive or active form and are available in low, high, and ultra high frequency.
 
NFC on the other end is referred to as a high frequency RFID and offers a more secure data exchange. Unlike RFID devices, NFC devices participate in peer-to-peer communication and can act as both readers and tags. Typically, NFC devices have a range of no more than 1.5 inches whilst RFID devices can cover up to 82 feet.

What is NFC?

NFC, also known as near field communication, is a set of communication protocols that connects two electronic devices typically within a distance of 1.5 inches. NFC can also be used to connect with wireless devices.

In door locks, the principal working mechanism for NFC is that it communicates with smart door locks to open and close them using different methods, including waving the phone. Keep in mind, however, Apple devices do not allow third party access to the NFC chip in phones.

What is RFID?

RFID is a radio frequency that uses electromagnetic fields to identify tags attached to devices such as door locks. The RFID technology uses a tiny radio transponder, receiver, and transmitter to send and receive command signals.

In practice, RFID technology works by using electromagnetic fields with a reader that automatically identifies digital data encoded within the RFID tags. The tag is typically represented by a card or similar tool.

How does an RFID lock work?

RFID locks feature a simple operational design. They primarily use cards as tags that help to send signals at a particular frequency to the tag/card reader. A chip embedded underneath the lock allows the transmission to happen. The card reader on the door dissects the signal and prompts the lock to open.

Once opened, the door can be released and as soon as it is shut, the lock will automatically latch. For the system to work, the card has to be in close proximity to the card reader on the door lock.

The NFC / RFID Door Lock Verdict

With the best RFID and NFC contactless door locks, home and office security will never be the same. You’ll no longer have to agonize about whether or not your home is safe. Additionally, the door lock systems offer access and control to your home or office doors beyond locking and unlocking.
