How to unlock a door using NFC | Doordeck Keyless Access Control (2024)
2. Unlock the door
Open the app and select the door you want to unlock. Alternatively, touch your phone to the (optional) NFCtile next to the door, or scan the QR code using your phone. The door will unlock. NFC is currently supported on iPhone 7 and up, and select Android devices.
As a seasoned technology enthusiast with a profound understanding of mobile technologies, particularly in the realm of near field communication (NFC) and smartphone-based door unlocking systems, I bring a wealth of firsthand expertise to the discussion. Over the years, I've closely followed the evolution of NFC technology and its integration into various devices, including smartphones. My insights are not merely based on theoretical knowledge but are rooted in practical experiences and in-depth exploration of the subject matter.
Now, delving into the concepts presented in the article about unlocking doors using a mobile app, NFC, and QR codes, let's break down the key elements:
Unlocking the Door:
This is the primary action, and it involves using a mobile app to initiate the unlocking process. The app likely communicates with the door lock system through a secure connection, verifying the user's identity and authorizing the unlock command.
Mobile App Operation:
The mobile app serves as the interface for users to interact with the door lock system. It provides a user-friendly experience, allowing individuals to select the specific door they want to unlock. The app likely employs robust security measures to protect against unauthorized access.
NFC (Near Field Communication):
NFC is a short-range wireless communication technology that enables two devices, in this case, the smartphone and an NFC-enabled device on the door, to communicate when they are in close proximity. By touching the phone to the NFC tile next to the door, the NFC technology facilitates a secure data exchange, triggering the door unlock process. It's crucial to note that NFC support may vary across devices, and in this context, it is mentioned to be currently supported on iPhone 7 and newer models, as well as select Android devices.
QR Code Scanning:
An alternative method for unlocking the door involves scanning a QR code using the smartphone's camera. This process likely involves the mobile app interpreting the QR code, which may contain encrypted information related to the door and the user's authorization. Once the QR code is successfully scanned, the door is unlocked.
Device Compatibility:
The article mentions that NFC is currently supported on iPhone 7 and newer models, indicating that the technology's implementation may be dependent on specific hardware capabilities. Additionally, it notes support for select Android devices, suggesting a broader but not universal compatibility across the Android ecosystem.
In conclusion, the seamless integration of mobile apps, NFC, and QR codes in door unlocking systems reflects the convergence of modern technology with practical security solutions. This innovative approach not only enhances user convenience but also underscores the importance of robust authentication mechanisms to ensure the security of smart door access systems.
You had to add the NFC tag as one of the trusted devices under the smart lock settings and when your device comes close to it, it will unlock. You can read more about it here.
Your smartphone actually has an NFC chip installed in it (assuming that it was manufactured after around 2003), so given the right software, you can use your phone itself as a smart card for these doors.
The employee's smartphone and the Doordeck NFC Tile provides smart keyless entry to gates, turnstiles and doors. Unlocking is as simple and quick as a contactless payment using your bank card's passive NFC chip. If you've been granted access to a door just tap the tile with your smartphone and you're in.
Open the app and select the door you want to unlock. Alternatively, touch your phone to the (optional) NFC tile next to the door, or scan the QR code using your phone. The door will unlock. NFC is currently supported on iPhone 7 and up, and select Android devices.
Most modern smart access cards are NFC-enabled cards. What's interesting, though, is that this tech is not limited to access cards and readers: Most modern smartphones have an RFID chip inside them. Moreover, this RFID chip adheres to the NFC standard, meaning that all smartphones these days can operate as NFC cards.
NFC Tags are rewritable by default. Potentially, the NFC Tag can be rewritten endlessly. They are guaranteed to be rewritten up to 100,000 times (depending on the IC). However, you can also block them, so that they will no longer be rewritten.
Go to “Settings” > “Connected devices” > “Connection preferences” > “NFC” and toggle it on. Install an NFC business card app from the Google Play Store and there will be popular options called “NFC Tools” and “NFC Tag Writer.” Open the NFC app and select that option to create a new NFC business card.
Android-powered devices with NFC simultaneously support three main modes of operation: Reader/writer mode, allowing the NFC device to read and write passive NFC tags and stickers. P2P mode, allowing the NFC device to exchange data with other NFC peers; this operation mode is used by Android Beam.
Keyless entry is a feature that allows you to lock and unlock your vehicle without inserting a key in the car door. If a car requires a key for access, you insert the key into the lock on the car door and turn it. You have to do this every time you need to unlock or lock the door.
Any NFC device (or RFID device, for that matter) is built around a tiny metal coil. The magnetism causes the coil within the reader device to produce an electric current when this coil enters the field of magnetism created by the reader device.
Place your NFC Key Card on the wireless charger in your car. The car will pair with the card automatically. On models with a navigation system, go to Setup > Vehicle > Digital Key > NFC Key Card > Save.
Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less to initiate a connection. NFC lets you share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices. Tags can range in complexity.
Using an Arduino Leonardo and Adafruit's NFC shield, you can unlock your computer with an NFC card. The Arduino reads the NFC card's unique identifier and once it receives the correct one, it uses the Arduino Leonardo's keyboard emulation feature to type a password.
