NFC capabilities in iPhone

The built-in contactless communication chip in the working stuffing of the phone opens up to the user extended possibilities of using short-range signals:

NFC on iPhone

Apple was one of the first to integrate contactless technology into its smartphones. It will be useful for users to know contactless communication. what it is, is there NFC in the phone, how to enable this function on the iPhone, and what additional settings may be needed.

Technical parameters of the chips in the iPhone

Parameter Unit measurements Meaning
Minimum interaction distance cm 0.5
Maximum interaction distance cm twenty
Data encoding method Manchester
Baud rate cbaud 424
RF signal frequency MHz 13.56
Connection mode Passive: receive only

The milliseconds during which the connection is established and the operation is performed, as well as the small radiation radius, allow NFC technology to be classified as a safe method for transferring confidential data from device to device.

What is NFC in iPhone

An NFC chip is a small, flat (round or square) chip made of flexible materials. The compact size allows the chip to be mounted even in ultra-thin iPhones. The activation and interaction technology is based on the generation of an electromagnetic field over short distances. Generation is carried out through a special loop antenna installed both in the source and in the consumer. Contactless is not available for all iPhone models.

Option is supported by models from iPhone 5s and up.

NFC setup

The NFC option on iPhone 6 and later does not require special signal activation. Built-in chip automatically generates and receives radio wave message when approaching an active or passive source.

In case of iPhone, manual activation and optimization of contactless communication is not required.

But in order to activate the capabilities, a number of actions are required.

Payment function activation:

  • Set identification and security features for Touch ID, iCloud.
  • Sign in to the Wallet app.
  • Find and activate the “Add Card” action.
  • Enter card details manually or take a photo of it.
  • Print holder’s name, expiration date and CVV code.
  • Confirm the correctness of the data via the code from the SMS.
  • Wait for the message “Card activated”.
  • Installing the NFC Writer software.
  • Scanning a tag.
  • In the Tag Emulation field, enter the ID number of the tag.
  • Activating and ending emulation.
  • The tag is paired with a device.

The article contains information on what the contactless option in the iPhone is, what its capabilities and technical parameters are, which iPhone models are equipped with a built-in chip, how to enable NFC on the iPhone, and what additional steps are required in order to start using the full functionality The number of applications and additional services for the iPhone is not yet as diverse as for androids, but the developers are actively working to expand the possibilities of using contactless communication in Apple gadgets.

How to enable real NFC on your iPhone in 1 minute

Today I will tell you how to make NFC on iPhone really useful. Not even so: we will actually turn it on.

The iPhone has had the module itself for many years, and it is completely freely used by the Apple Pay contactless payment system.

But if you try to connect any accessory to the iPhone via NFC, you will be disappointed. precisely, it waited until the last moment.

By default, iOS ignores NFC tags in wireless headphones and portable speakers. the ones designed for quick connections. It’s a pity, because it’s very convenient: you bring the headphone case to the iPhone, and it automatically connects to your earplugs.

Android has done this since time immemorial, so why are we worse? It turns out to be almost nothing. thanks to Commands in iOS 13.

I was pleased with the positive reaction to the previous post about automating the connection of Airpods to Apple gadgets. Anyway, Commands in iOS 13 is a really powerful tool, learning which brings tangible benefits.

So I decided not to stop and offer you something cooler.

What are we going to do to make NFC work as intended?

Many good wireless headphones and portable speakers have NFC support. In 99% of cases, it allows you to skip the pairing procedure through the Bluetooth menu. Just bring your smartphone to the accessory. and you’re done.

Apple has blocked NFC in the iPhone for a very long time for any purpose other than Apple Pay, so iPhone owners have long been accustomed to ignoring the feature in all accessories. Now let’s get out of the habit.

Thanks to the instructions below and the iOS 13 Commands, you can use NFC in your headphones and speakers to connect your iPhone to them with one swipe without any Settings or menus at all.

Instruction. We turn on the connection to headphones and speakers via NFC

iPhone with iOS 13. iPad won’t work, iPod touch too, they just don’t have NFC

▸ wireless headphones or speakers with an NFC tag. If the accessory does not have an NFC tag, it doesn’t matter. Even your bank card can serve it, as I wrote about here

How do you know if your accessory has NFC? The NFC emblem is applied to the body of the accessory next to or directly above the location of the tag. For successful pairing, it must be directed towards the back of the smartphone. The range is low and is a maximum of a couple of centimeters.

Before starting the setup, make sure that the accessory is connected to your gadget right now, this is important. Go.

Open Commands and go to the Automation tab. If accidentally deleted, just download again from the App Store.

Click on in the upper right corner or immediately select Create automation for yourself.

In the list that opens, scroll down to the NFC item. Tap on Scan opposite NFC tag.

We bring your headphones or speakers with the NFC tag to the upper part of the back of the iPhone. where it has a camera.

Nothing happens? Do not make any sudden movements and hold the mark under the iPhone for at least a second before moving it. for some reason, the initial recognition of a tag in iOS 13 takes much longer than it will take after setup.

You can also use any NFC tag, not just the one built into your headphones or speakers. In addition to bank cards, a pass from the office or an NFC sticker from AliExpress can serve as a tag. Thus, the quick connection function can be added to any Bluetooth speaker. The main thing is not to lose the mark itself.

As soon as the iPhone finds the tag of the accessory, it will offer to name it. Write and continue.

Now we add a new action that will be performed when the iPhone finds this NFC tag. Select Scripts, scroll down and click Set Playback Location.

In the list that opens, select the headphones or speakers that will connect to the iPhone when you bring it to the NFC tag. In my case, these are Sony WF-1000XM3 headphones.

If nothing is listed, you have not connected the accessory to your iPhone in advance. Do this and return to the current point of the instruction.

We’re almost done. It remains only to disable the Ask before launch option and confirm your choice.

Now, every time you bring your iPhone to the included headphones or speakers, they should connect to each other.

Unlike Android, iPhone cannot be forced to connect to unknown (previously unpaired) devices through the Automation we just created. We are waiting for iOS 14 and further indulgences for NFC from Apple.

How to set up NFC tags from iPhone?

Do you want to learn how to work with NFC tags on the iPhone or just understand the technology? Follow the link and read how NFC tags can make your life easier and how to use them yourself!

Smartphones have already made our lives much easier. Now large companies are concentrating on the development of automation of routine processes, controlled via a smartphone.

As usual, Apple is leading this technology race. Now we will not touch on their HomeKit smart home system. In addition to her, they are actively working to improve the mobile operating system iOS.

For several generations of iPhones, users have been able to contactlessly pay for purchases through the NFC module and the Apple Wallet proprietary application. With the release of iOS 13, the owners of Apple smartphones have the opportunity to expand the use of the module. For example, interacting with NFC tags.

An NFC tag is a small chip on which the user can write some information. They only store data, so they don’t require electricity. They are produced in the form of stickers, key rings and cards.

How to write tags to an NFC tag?

If the user wants to store his own information on the NFC tag, he will have to download a separate application for configuration. We are talking about the example of the application “NFC Tools”, but the logic of work for such software is about the same.

Download and run the application. Next steps:

  • Click on the “Write” button.
  • Select “Add Record”.
  • Select the desired item that you want to write to the NFC tag.
  • Place the mark on the back of your smartphone and wait until the end of the recording.

If desired, you can erase the recorded data from the mark or overwrite the information.

If you need to trigger commands from the Commands app, it’s even easier to configure them. This application has a built-in function for triggering a command upon contact with an NFC tag.

enable, iphone

It’s just that when you set up a new command or a whole scenario, there will be an item “NFC” at the bottom of the menu. Open it and tap the “NFC” line again. Scanning of marks starts. All that remains is to attach a blank label and sign it in the app. After scanning, add whatever you want to its functions.

How an NFC tag makes our lives easier?

By itself, an NFC tag is a rather useless thing. The memory capacity is not enough to record something significant. At most, this is a link to download something or some kind of video on YouTube. You can customize the launch of the application, but this is a rather strange case. Apple has not just introduced their support only with iOS 13 for a reason.

An NFC tag in combination with the Commands application becomes a powerful and convenient tool for automating routine tasks. You can configure the tag so that when you bring the iPhone to it, a programmed script will automatically start. How many tags you have, so many scenarios.

Several practical cases of using NFC tags:

  • Hang the NFC tag at the exit from the apartment. When scanning, the iPhone itself will show the travel time to the office, taking into account traffic jams, tells the weather forecast, and launches the smart home mode “I’m leaving”.
  • Before going to bed, we put our smartphone in one specific place. You can stick an NFC tag on this place, and by applying a smartphone, it can work: the alarm clock is set, the “Do not disturb” mode is turned on, the “Good night” mode is turned on in the smart home system (everything unnecessary is turned off, the necessary turns on), Siri tells the weather forecast on tomorrow.
  • Paste some tags in the car. You will be able to automatically open and close the garage, navigate your way to different points of the city.

Of course, these are not all possible cases. The Internet is full of real stories of the use of NFC tags for home and office. You can hit on futurism, tape a label under the wallpaper and set it to open a secret door in the house or an automatic emergency call to the rescue services.
