NFC tags are a neat, unassuming way to get your phone to do specific things automatically, based on location or context. Think of them as tiny, programmable switches. Essentially, you tap your phone on one of these tags, and an action you’ve pre-set – like turning on Wi-Fi, launching an app, or sending a quick message – happens without you needing to manually open settings or apps. It’s pretty straightforward once you get the hang of it, and it can save you a few taps here and there throughout your day.
NFC, or Near Field Communication, is a short-range wireless technology that lets two devices, like your phone and an NFC tag, communicate when they’re close together – usually within a few centimeters. It’s the same tech used for contactless payments.
What Makes NFC Tags Practical?
The beauty of NFC tags for automation lies in their passivity and simplicity. They don’t need power, and they’re small enough to stick almost anywhere. You can program them once and they’ll trigger the same action every time your phone taps them. This means you can create context-aware shortcuts without having to remember to activate them yourself or rely on more complex location-based services that can drain your battery.
NFC vs. Other Automation Methods
Compared to, say, geofencing (which uses GPS to trigger actions when you enter or leave an area), NFC tags are more precise and often quicker. Geofencing can be a bit slow to react and may not always pinpoint your exact location accurately enough for certain tasks. Tasker profiles, while incredibly powerful, require opening an app and selecting a profile. NFC tags offer a physical, tap-to-trigger interaction that’s quick and tactile. For simple, repeated actions in specific places, they’re a good fit.

Getting Started: What You’ll Need
Before you dive into programming, you’ll need a few things to make this work. It’s nothing complicated or expensive, but it’s crucial to have the right tools.
Your Smartphone
Most modern smartphones, both Android and iOS, support NFC.
Android Devices
If you have an Android phone, chances are it has NFC. You can usually find the NFC setting in your phone’s ‘Connected devices’ or ‘Bluetooth & device connection’ settings, often under a section like ‘NFC and contactless payments’. Make sure it’s switched on.
iOS Devices
For iPhones, NFC has been present since the iPhone 6. However, for automation with NFC tags, you’ll need an iPhone XS or newer to use the native “Automations” feature in the Shortcuts app. Older iPhones might be able to read NFC tags, but typically only for a handful of pre-approved actions or specific apps – not broad automation.
NFC Tags
These are small, flat stickers or key fobs that contain a tiny NFC chip.
Types of NFC Tags
There are different types of NFC chips (like NTAG213, NTAG215, NTAG216), which mostly vary in their storage capacity. For simple automation triggers, even the smallest capacity tags like NTAG213 are usually sufficient. Don’t worry too much about the specific chip type unless you plan to store a lot of data on the tag itself, which isn’t usually necessary for automation triggers.
Where to Buy Them
You can easily find NFC tags online from retailers like Amazon, eBay, or specialized electronics stores. They’re relatively inexpensive, often sold in packs. Just search for “NFC tags” or “NFC stickers.”
An NFC Programming App
While some phone’s native automation tools (like Apple’s Shortcuts) can write to tags, it’s often easier and more versatile to use a dedicated app for programming, especially on Android.
For Android
Apps like “NFC Tools” by wakdev or “NFC TagWriter by NXP” are popular and user-friendly choices. They allow you to write various types of data to NFC tags, including the kind of data that signals your phone to perform an automation.
For iOS
On iOS, the Shortcuts app is your primary tool for creating NFC automations. While it can read tags, writing to them for basic automation is usually handled automatically when you set up an automation. If you want to write other data to a tag, “NFC Tools” also has an iOS version.
Basic Steps to Set Up an NFC Automation
The process generally involves programming the tag first (telling the tag what to say) and then teaching your phone what to do when it hears that message.
Programming the NFC Tag (Android Focus)
Let’s use “NFC Tools” as an example, as it’s quite popular and versatile.
Step 1: Open Your NFC Programming App
Launch the “NFC Tools” app on your Android phone.
Step 2: “Write” Tab
Navigate to the “Write” tab within the app. This is where you’ll define what information is stored on the NFC tag.
Step 3: Add a Record
Tap “Add a record.” You’ll see a list of different data types you can write. For triggering phone automation, you often want to write a simple text record or a URL that your phone’s automation app can then interpret.
Writing a Text Record
A simple text record like “Home_Automation_WiFi” or “Car_Mode_ON” is often all you need. This text simply acts as a unique identifier for your phone to recognize.
Writing a URL
Alternatively, you can write a simple URL, even a non-existent one, like http://automation.home.wifi. The main thing is that it’s unique to this tag and action.
Step 4: Write to Tag
Once you’ve entered your chosen text or URL, tap “Write” and then gently tap your phone against the NFC tag. You should hear a confirmation sound, and the app will confirm the data has been written.
Setting Up the Automation on Your Phone
Now that your tag has data on it, you need to tell your phone what to do when it reads that data.
For Android (Using Tasker or Similar)
Android’s automation can be very powerful with apps like Tasker, Macrodroid, or Automate.
Tasker Example: Recognizing the NFC Tag Data
- Create a New Profile: In Tasker, go to the “Profiles” tab and tap the ‘+’ button.
- Select Event: Choose “Event” from the list.
- Find NFC: Scroll down and select “NFC Tag” (or similar, depending on the version/plugins).
- Configure NFC Tag Event: Here, you’ll specify what data Tasker should look for.
- If you wrote a text record: Enter the exact text you wrote (e.g., “Home_Automation_WiFi”) in the “ID” or “Content” field.
- If you wrote a URL: Enter the URL you wrote.
- Create/Select a Task: Once the profile is set up, you’ll be prompted to create a new task or select an existing one. This task will contain the actions your phone performs.
Building an Automation Task (Android)
Within the task, you can add various actions:
- Wi-Fi On/Off:
Net > Wi-Fi > Set: On - Bluetooth On/Off:
Net > Bluetooth > Set: On - Launch App:
App > Launch App > [Select Your App] - Change Brightness:
Display > Display Brightness > Level: [0-255] - Set Volume:
Audio > Media Volume > Level: [0-15] - Send SMS:
Phone > Send SMS > [Number, Message] - Open a Webpage:
Net > Browse URL > [URL]
Saving and Testing
Save your Tasker profile and task. Now, when you tap your phone on the NFC tag you programmed, Tasker should detect the unique data and execute the associated task.
For iOS (Using Shortcuts App)
Apple’s Shortcuts app has built-in NFC automation capabilities for newer iPhones.
Step 1: Open Shortcuts App
Launch the Shortcuts app on your iPhone.
Step 2: Automation Tab
Tap on the “Automation” tab at the bottom of the screen.
Step 3: Create Personal Automation
Tap “Create Personal Automation” (or the ‘+’ icon in the top right, then “Create Personal Automation”).
Step 4: Scroll to NFC
Scroll down the list of triggers and select “NFC.”
Step 5: Scan Your Tag
Tap “Scan” and then touch your iPhone to the NFC tag you want to use. Give the tag a name (e.g., “Desk Wi-Fi”). This name is for your reference within Shortcuts.
Step 6: Add Actions
Tap “Next” and then “Add Action.” Here, you’ll choose what your iPhone does when it scans this tag.
Building an Automation Action (iOS)
Just like with Android, you have many options:
- Set Wi-Fi: Search for “Set Wi-Fi” and choose “Turn Wi-Fi On/Off.”
- Set Bluetooth: Search for “Set Bluetooth” and choose “Turn Bluetooth On/Off.”
- Open App: Search for “Open App” and select the app from your list.
- Change Brightness: Search for “Set Brightness” and adjust the percentage.
- Set Volume: Search for “Set Volume” and adjust the percentage.
- Play Music: Search for “Play Music” and select a song or playlist.
- Send Message: Search for “Send Message” and configure the recipient and message.
Saving and Testing
Once you’ve added all your desired actions, tap “Next.” On the next screen, you’ll see an option “Ask Before Running.” For most automations, you’ll want to toggle this OFF so it runs automatically without prompting you. Then tap “Done.” Now, tapping your iPhone on the NFC tag should trigger your set actions.
Practical Automation Examples to Try
Here are some real-world scenarios where NFC tags can help streamline your daily routines.
Home Automation Triggers
NFC tags can make common home actions quicker and more intuitive.
Desk Mode
- Tag Location: Under your desk or on your monitor.
- Action: Tap your phone on the tag when you sit down.
- Automation: Turn on Wi-Fi, silence ringer (except for important contacts), set media volume to a specific level, launch your calendar or to-do app.
Bedside Routine
- Tag Location: On your nightstand.
- Action: Tap your phone before going to sleep.
- Automation: Turn off Wi-Fi, turn on “Do Not Disturb,” set an alarm for the morning (if not already set), open your sleep tracker app.
Guest Wi-Fi
- Tag Location: Near your main door or on a prominent surface.
- Action: Guests tap their phone (or your phone) on the tag.
- Automation: Display a Wi-Fi password (text record on the tag itself, or launch an app that shows it), or even automatically connect to a guest network (if you can configure that in your phone’s automation app).
Car Automation
Get your phone ready for driving the moment you get in.
In-Car Mode
- Tag Location: On your car’s dashboard or console.
- Action: Tap your phone on the tag when you get in the car.
- Automation: Turn on Bluetooth (to connect to your car stereo), launch your preferred navigation app (e.g., Google Maps, Waze), set media volume for music or podcasts.
Commute Ready
- Tag Location: In your car, for when you’re about to start your commute.
- Action: Tap before you begin driving.
- Automation: Send a quick “On my way!” message to a specific contact, start a driving-focused app.
Work and Public Spaces
NFC tags aren’t just for home; they can be useful in other environments too.
Meeting Mode
- Tag Location: On your office desk or inside a meeting room.
- Action: Tap your phone as you start work or enter a meeting.
- Automation: Silence your phone, set it to vibrate, or launch apps you use for meeting notes.
Public Transportation Commute
- Tag Location: On your backpack or inside your wallet (where it’s easy to tap).
- Action: Tap when you board a train or bus.
- Automation: Open your e-reader app, launch your podcast player, or enable a specific transit app.
Advanced Ideas and Tips
Once you’re comfortable with the basics, you can explore more complex automations.
Toggle Actions
Instead of just “Turn Wi-Fi On,” you can program a single tag to toggle Wi-Fi (if it’s off, turn it on; if it’s on, turn it off). This usually requires a slightly more complex script within Tasker or a dedicated “Toggle” action in Shortcuts.
Chained Automations
You can sometimes create automations that trigger other automations, or combine multiple actions into one robust script. For example, a “Good Morning” tag could not only turn off Do Not Disturb but also tell your smart home hub to turn on the lights and make coffee (if your phone’s automation app integrates with those services).
Protecting Your Tags
While NFC tags are generally durable, extreme heat or bending can damage them. If using them outdoors or in high-traffic areas, consider more robust, weatherproof tags.
Rewriting Tags
You can usually rewrite NFC tags multiple times. If you change your mind about an automation, just open your NFC programming app and write new data to the tag.

| Turn on/off Wi-Fi | Yes |
| Launch specific app | Yes |
| Adjust phone settings | Yes |
| Send a text message | Yes |
| Play music | Yes |
Sometimes things don’t work perfectly the first time. Here are a few common hiccups and how to address them.
Phone Doesn’t Read the Tag
- NFC is OFF: Double-check that NFC is enabled in your phone’s settings.
- Incorrect Placement: Ensure you’re tapping the phone’s NFC sensor directly to the tag. The sensor is usually near the top back of Android phones or in the upper front for iPhones. Experiment with slightly different tapping positions.
- Tag Damage: While uncommon for new tags, a physically damaged tag may not respond. Try a different tag.
- Phone Case Interference: Thick phone cases, especially those with metal, can sometimes block the NFC signal. Try removing the case.
- Background Apps: Sometimes other NFC-reliant apps can interfere. Try closing other apps and retrying.
Automation Doesn’t Trigger
- Mismatched Data: Ensure the data you programmed on the tag exactly matches what your phone’s automation app is looking for. Even a single extra space can prevent it from working.
- App Permissions: Make sure your automation app (Tasker, Shortcuts, etc.) has all the necessary permissions to perform the actions you’ve set (e.g., access to Wi-Fi, Bluetooth, location).
- Automation Disabled: Check if the automation itself is active/enabled within the app.
- “Ask Before Running” (iOS): If you enabled “Ask Before Running” in iOS, you’ll get a notification to confirm before each run. While useful for testing, disable it for seamless automation.
- Background Restrictions (Android): Some Android models have aggressive battery optimization that can restrict background app activity. Ensure your automation app is excluded from these optimizations.
iOS “Run from Shortcuts” Prompt
For some actions in iOS, even with “Ask Before Running” disabled, you might get a banner notification that says “Running your automation from Shortcuts.” This isn’t an error but a security measure; it simply indicates that Shortcuts is performing the action. There’s no way to completely disable this banner for all automations currently, but it doesn’t stop the action from running.
