What is NFC? What does NFC stand for?

NFC allows for the exchange of digital information, secure transactions and connection of electronic devices (smartphones, tablets, laptops, wearables) with just a touch. NFC stands for Near Field Communication. The communication range is short, of a maximum of about half an inch between the NFC tag and NFC reader.

The NFC chip built into modern smartphones is most commonly known as a tap-to-pay technology, however it can be used for a variety of functions, including access control for doors!

How does NFC work?

NFC works through a magnetic field from an NFC reader device being brought near to an NFC tag to create an electric current that is passed through the coil activating a transfer of stored data on the tag to the reader device.

NFC active vs passive

Active NFC devices can send and receive data, allowing for storing and transfer of information. Doordeck encompasses active NFC technology.

Passive NFC can only send data. It is a one way transfer of communication. Passive NFC devices can run without power. e.g. key cards.

RFID vs NFC

RFID vs NFC

NFC is part of the RFID family however is designed for security. RFID can exchange data long range through radio waves, and like NFC between a tag and reader. Great for asset location and logistics.

However… The short communication range of NFC technology makes for a much more secure exchange of sensitive data, ideal for secure payments or in Doordeck’s case secure door access.

NFC vs Bluetooth

The main difference between NFC and Bluetooth is the frequencies they operate on. Bluetooth has a much higher frequency than NFC meaning its transmission time is much quicker. Additionally Bluetooth trumps NFC on range, with a transmission range of up-to 10m whereas NFC technology is only up-to half and inch. However with NFC having a lower frequency it means it uses less power when transferring data. NFC connection is also much simpler and secure with it only requiring a tap to link two devices.

Some of Our Clients

We have two sites each with different access control systems, neither of which support smartphone access. We were worried we'd have to start from scratch at huge cost but the Doordeck system has slotted in right alongside. It's inexpensive, simple to install, and easy to operate.

Tom

Director , Cowork

Since integrating Doordeck with our existing ACT door access control hardware we have been able to provide smartphone zero touch door entry to our tenants, particularly important during these times where tenants want to feel at ease.

Freddy

CEO, Savvy

EIG has been using Doordeck since 2016, I can strongly recommend their SaaS solution works perfectly alongside my existing Paxton Door access control hardware. As my staff have been using Doordeck for many years they had the added confidence that EIG were already ahead of the times.

Lisa

FD , Estate Insurance Group (EIG)

Being a multi-tenant landlord, I need to be able to provide access for multiple trades people, and have visibility of the comings and goings to ensure my buildings are secure and run efficiently. Being able to issue visitor passes for specific entry and exit times solves the need to be at the building to let the workmen in.

Nick

Chairman, Property Consolidation LLP

Doordeck was the logical access system for us. The UI is intuitive and easy to navigate, and when we need support the team are beyond helpful. We'd highly recommend Doordeck to anyone.

Sarah Martin

Programme Manager, Cisco

Big fan of Doordeck! The app is really easy to use and if you have any problem the support team is really quick and helpful. Everyone in the office comments on how fantastic it is.

Christill Asamoah

Manager, Rainmaking Loft

It was simple and straight forward to operate, easy and simple to install on my Android phone. I am really impressed. This block also had electronic gates, which I did use, again worked well to get in.

Mark

Electrician, RMG managed property

I love Doordeck. It's made my life easier and helped provide additional logs of all time stamps comings and goings from the building. It’s also help me to save money and time.

Arilma

Office Manager, Property Consolidation LLP

It seems super safe. The app is really well designed and easy to use. The widget is very convenient to open the door from a distance (especially in times of Covid, when it is nice to avoid touching door handles, etc).
