The Unknown Power of NFC in Your iPhone
Your iPhone has a chip you probably never think about. The NFC chip . Hidden away invisibly inside your device. You might use it every day without even realizing it. When paying at the supermarket. When checking in on the train. But here's the thing: most iPhone users aren't even using 10% of what this technology is capable of.
This tiny chip transforms your phone into a digital keychain, payment card, and automation hub all in one. Starting with the iPhone 6, this technology has been standard in every newer model . Yet, for many, it remains a mystery what NFC actually does. And that's a shame. Because this inconspicuous feature increasingly determines how smoothly your day runs—from your morning coffee to automatically dimming your lights when you get home.

What exactly is NFC?
NFC stands for Near Field Communication. It's a wireless technology that allows devices to communicate with each other over a distance of up to 4 centimeters. This short distance was deliberately chosen for security. Your iPhone practically has to be held against another device for data to be exchanged.
The technology works through electromagnetic fields. When two NFC devices come close together, a connection is established. This connection can be used for various purposes, from payments to file sharing.
The evolution of NFC in Apple devices
Apple first introduced NFC in 2014 with the iPhone 6 and 6 Plus. Initially, its functionality was limited to Apple Pay. Developers only gained access to the chip for other applications starting with iOS 11 (2017). iOS 13 added the ability to read NFC tags without special apps.
Practical applications in daily life
Contactless payment
The most popular application remains Apple Pay. You can pay at millions of payment points worldwide. In the Netherlands, virtually every store accepts contactless payments. The process is simple: unlock your phone with Face ID or Touch ID, hold it against the payment terminal, and you're done.
The advantage? You no longer need to carry physical cards. Plus, it's more secure than a regular debit card. A unique code is generated for every transaction. Your real card number is never shared with the merchant.
Public transport
In a growing number of cities, you can check in with your smartphone. Amsterdam, Rotterdam, and The Hague already support this. You add your public transport card (OV-chipkaart) to the Wallet app. Then, you check in by holding your device against the reader. It even works when your battery is low thanks to the energy-saving backup mode.
Smart home automation
NFC tags are small stickers you can stick anywhere. Program them using the Shortcuts app on your iPhone. Some examples:
- A tag on your bedside table that automatically sets your alarm and activates do not disturb
- A sticker on the front door that turns off your lights and lowers your thermostat
- A tag in the car that starts navigation and opens your favorite playlist
These tags cost only a few euros each. They don't require a battery because they're powered by your phone's electromagnetic field.
Which iPhone models support NFC?
All iPhones from the 6th generation onward have an NFC chip. But there are differences in functionality:
iPhone 6 to iPhone X: NFC only works for Apple Pay
iPhone XS and later: Full NFC support including background tag reading
This means that newer models can scan NFC tags without having to open an app. The device automatically detects when a tag is nearby.
Differences between models
The latest generation has improved NFC performance. The iPhone 15 series can read tags from a greater distance (up to 5 centimeters). The reading speed has also been increased. This makes it more convenient to use in crowded environments like train stations.
Privacy and security
Many users worry about privacy when it comes to wireless technology. With NFC, these concerns are largely unfounded. The technology only works at very short distances. No one can read your data unnoticed from a distance.
Apple has built in additional security measures. Payments always require authentication via Face ID, Touch ID, or a passcode. Apps can't simply access the NFC chip; they must first request permission.
Tips for safe use
- Turn off NFC when not in use (via Settings > General > NFC)
- Check which apps have access to NFC
- Use only reliable NFC tags from well-known brands
- Be careful with tags in public spaces
Practical tips for beginners
Setting up your first NFC automation
Start simple. Buy a set of NFC tags online (usually around €10 for 10). Download the free Apple Shortcuts app. Create a new automation:
- Open Assignments and go to "Automation"
- Tap the plus sign
- Select "Create Personal Automation"
- Select "NFC"
- Scan your tag
- Add actions (for example: turn Wi-Fi on/off)
Experiment with simple commands first before creating more complex automations.
Troubleshooting
Is NFC not working as expected? Check these points:
- Is NFC enabled in settings?
- Do you have a case that can block NFC? (Metal cases are problematic)
- Are you holding the phone in the right position? (The NFC antenna is located at the top near the cameras.)
- Is your software up to date?
The future of NFC
The possibilities continue to grow. Digital car keys are becoming increasingly popular. BMW, Mercedes, and other brands already support them. Your iPhone literally becomes your car key. Digital IDs are also on the way. Several countries are experimenting with digital passports and driver's licenses.
Healthcare is also seeing developments. Medical devices can exchange data with your phone via NFC. Think of blood glucose monitors for diabetics or blood pressure monitors.
What can we expect?
Apple is working on expanding its NFC capabilities. Rumors suggest that future models will be able to maintain multiple NFC connections simultaneously. This would enable new applications such as sharing files with multiple people simultaneously.
Integration with augmented reality is also being explored. Imagine pointing your camera at an NFC tag and seeing information instantly appear on the screen. Museums are already experimenting with this for interactive exhibitions.
Conclusion for daily use
The NFC chip in your iPhone is more than just a payment method. It's a versatile technology that can simplify your life. Whether you want to save time with automation, pay more securely, or are simply curious about its possibilities – NFC offers value for everyone.
Start small with contactless payments if you're not already. Then experiment with a few inexpensive NFC tags for home automation. Before you know it, you'll be using the technology daily without even thinking about it. Exactly as technology was meant to be: invisible, yet incredibly convenient.
NFC makes your life easier
The NFC chip in your iPhone isn't a pipe dream, but practical technology that's already streamlining your daily routines. From contactless payments to home automation—the possibilities are literally in your pocket. The best part is, you don't have to be tech-savvy to get started.
Simply start using Apple Pay for your daily purchases and discover what else is possible. Whether you set up a few simple automations or go all-out for digital keys, NFC makes life just that little bit easier without you even thinking about it.
