How to enable NFC on iPhone

Technical parameters of the chips in the iPhone

Parameter Unit measurements Meaning
Minimum distance for interaction 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 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.

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 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.

Turn on NFC on Android

Enabling NFC on your smartphone is easy enough. You need to open the “Settings” or click on the gear on the notification shade to immediately get into the “Settings”. Next, select the “Connected devices” section.

To enable NFC, you need to drag the slider to the “On” position.

Now you can transfer files, pay via Google Pay.

Turn on NFC on iPhone

Methods for enabling NFC on iPhone are different from those for Android. To enable this technology, it is worth downloading the Apple Pay application from the Apple Store, which is designed to make contactless payments. After that, you need to open Wellet and allow him access to Apple Pay.

Add maps. You can scan them and enter your data from an iPhone or PC. The data is needed the following:

After you enter all the card details, an SMS with a verification code will be sent to your phone number. It must be entered in a special window (the Internet must be enabled on the phone). Next, you need to activate the fingerprint scanner or Face ID to protect your data from theft.

After these operations, a card for paying for services will appear in Apple Pay. If you click on it and bring the iPhone to the terminal for payment, then NFC will be turned on and the payment operation will take place, which is accompanied by a specific sound.

If you want to transfer a file via NFC, then the steps are as follows:

  • We open “Teams”, “Automation”. Click on the “” icon to create a new task.
  • Find the item “NFC”, “NFC Tag” and click “Scan”.
  • You need to bring the devices with the activated module to the back of the iPhone (where the camera is).
  • After the desired device is found, you need to select an action.

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 the ability to contactlessly pay for purchases through the NFC module and the Apple Wallet 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 talk about the example of the application “NFC Tools”, but the logic of 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.

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 implemented 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.
