Future iPhones Could Get Extended NFC Range for Easier Tap-to-Unlock

The NFC Forum announced NFC Certification Release 15 (CR15), introducing a change that boosts the potential read range of NFC devices. CR15 defines the certification program for compliance with the NFC Release 15 specification that was announced earlier this year.

CR15 allows devices to certify for a read range of up to 20mm, which is a meaningful improvement over the prior 5mm limit. The NFC Forum says that the range increase will improve the user experience by requiring less precise alignment for a connection.

Future Apple Watch and iPhone models could adopt the increased 20mm range, but existing devices won't benefit because the change requires updated NFC hardware.

For ‌iPhone‌ and Apple Watch users, the update could allow future Apple devices to activate hotel room doors, house doors, car doors, and other NFC-enabled devices from further away. NFC is used for short-range interactions, like unlocking a HomeKit-compatible door as the homeowner approaches or opening a hotel room door without a physical key. Apple technologies like HomeKit and hotel key wallet integration could be faster and more reliable with the change.

The 15mm increase means users won't have to align devices as precisely, but NFC will still be more secure than longer-range technologies like Bluetooth or Ultra Wideband. Devices that support the 20mm certification could be available in the coming months now that the testing and certification process is available.

Apple, Google, and other major tech companies are members of the NFC Forum, so Apple was likely involved in the specification upgrade.

This makes no sense to me - I always bring my device right up to the reader, and after hundreds of transactions over the years, I can’t recall ever having an issue due to range.

Historically, issues with NFC transactions have occurred because 1) The point of sale device’s software was slow or required the cashier to physically press a key to enable it; and 2) Particularly during early years of Apple Pay, it was often unclear whether it was supported at a given store.

And yes, I understand the new NFC range is still less than an inch.
And there were problems with the NFC readers being too powerful and picking up other cards in the area. I believe some UK retailers had problems around 2015 or so, where the wrong card was being picked up, even though the right card was being held up to the reader. Adding more range would make the problem worse. I keep my cards in a wallet with Faraday Cage built into it.

Still less than an inch. This does mean you could be more clumsy and still get a good read, though.

I wonder if new NFC hardware is required on the phone and device side or just the phone side.

This is such a cool feature and I’m glad that Apple is continuing to improve the technology behind it

I saw a video of this being demonstrated at one of the hotels that currently offers this a few few years ago:



I hope that more hotels continue to implement this technology because it’s definitely much better than the hotel keys that are provided directly (via the hotel’s app-based key)
