On September 12, 2017, Apple introduced the new iPhone 8, iPhone 8 Plus and iPhone X, along with the new iOS 11 operating system, released a week later.

Apple had already announced the presence of Core NFC, a package of SDK libraries within iOS 11 that allow reading Tag NFC. By updating to iOS 11, iPhone 7 and 7 Plus can read NFC Tag. iPhones 6 series and SE are actually equipped with an NFC sensor, but can be used for mobile payments only.

Can iPhone read NFC Tags?

The answer is yes, even if it depends on the model, and with some differences over Android and Windows.

Below is a summary of the state of the art.

iPhone X

  • NFC Sensor can read NFC Tags, and manage mobile payments
  • However, a dedicated app is required to read Tags
  • Tags must contain an NDEF message

Can read NFC Tags

iPhone 8

iPhone 8 Plus

iPhone 7

iPhone 7 Plus

  • NFC Sensor can read NFC Tags, and manage mobile payments
  • Update to iOS 11 required
  • dedicated app is required to read Tags
  • Tags must contain an NDEF message

iPhone 6

iPhone SE

  • NFC Sensor can be used for payments only

CAN NOT read NFC Tags, without an external reader

iPhone 5 and earlier

  • No NFC Sensor

 

Which NFC chips are compatible with the iPhone?

The iPhone (from 7 onwards) are able to read NFC chips like:

  • NTAG®
  • ICODE®
  • MIFARE Classic®
  • MIFARE Ultralight®

However, we always recommend using NTAG® chips, as they are compatible with all NFC-enabled smartphones and tablets.

NFC and iPhone tags: differences with other operating systems

Apple devices behave a bit differently from Android for what concerns NFC technology.

iPhone X - NFC

  • An installed and open app is required
    An Android smartphone can detect an NFC tag without any particular application installed, as long as the phone is not in standby mode. As for the iPhone, iOS does not have any native support for reading NFC tags and performing actions on the local device. An app must be installed to implement these actions. Additionally, the app must also be open, otherwise Tags will not be detected. One of the apps available for reading Tags with an iPhone is NFC TagInfo by NXP.
  • NDEF messages only
    Another peculiarity of iOS is that it allows you to read only tags that contain an  NDEF message (NFC Data Exchange Format), so to speak, the standard commands defined by the NFC Forum: URL, V-Card, plain text, SMS, email, call. In iOS, unlike Android, there is no "launch application" command (a Tag programmed to open a specific app).
  • iPhones can't read Tag's UID
    With iOS you can not read the Tag's UID. As a result, all those applications that are based on UID reading, such as anti-counterfeiting or access control apps, are not possible with an iPhone, at least for now.
  • Read, but not write
    Finally, it's good to point out that iPhones can read NFC Tags, but can't program them. For programming, you must use an Android smartphone, or a PC with an NFC Encoder. Alternatively, Shop NFC allows you to purchase NFC Tags already encoded.

Our opinion on the future of the NFC

Apple's openness to NFC technology is certainly a huge boost for the Internet of Things (IoT) industry.

The implementation of the NFC sensor in the (now old) iPhone 6, although the features were limited to Apple Pay, had already made the general public aware of this technology, which until then was semi-unknown.

Now, with 3 new iPhone models that can read NFC tags, you can finally spread those NFC solutions related to consumer or marketing use.

On the one hand we have in fact the power of the Apple brand, that has the Midas touch, and its extraordinary power in communication. With the implementation of the NFC in the iPhone, the awareness of this technology makes a big leap forward, allowing the development of new and numerous projects.

On the other hand, we have an important slice of the market, consisting of the owners of an iPhone that, although not the majority of the mobile market, represents a portion of consumers who tend to spend more than an Android user.

These two elements make us believe that the NFC technology, after declining in these years in applications of traceability, logistics, anti-counterfeiting, access control, ticketing, can now find full development in the field of marketing. A field not entirely new to the NFC, but whereas before the Tag was almost always accompanied by a QR, now it can have its own dignity and be exhaustive and transversal, being able to be implemented by all the mobile operating systems in circulation.
