What Is FeliCa? Japan's NFC Standard, Explained
FeliCa is the contactless standard — known as NFC-F — behind Japan's Suica, PASMO, and Osaifu-Keitai systems. Here's how it works, where you'll run into it, and what your phone can and can't read from one.
What it is (one-paragraph answer)
FeliCa is a contactless smart card technology built by Sony, and inside the NFC standard it goes by a different name: NFC-F, or "Type F." It powers the instant tap-to-pay gates on Japan's trains and the e-money readers in its convenience stores. Watch someone breeze through a Tokyo ticket gate without breaking stride and that's FeliCa doing the work — a fast, encrypted handshake Sony designed decades before most of the world settled on a common contactless standard. Below: how it works, where you'll run into it, and what your phone — and NFCore — can actually read from one.
How it actually works
FeliCa runs on the same 13.56 MHz radio band as every other NFC technology, using Manchester coding at 212 kbit/s and requiring a proximity of about 10 cm or less — physically identical parameters to NFC-A and NFC-B. That range limit isn't unique to FeliCa. It's baked into the physics of near-field coupling, which we cover in more depth in why NFC has to be so close.
Where FeliCa diverges is the standard it's built on and the security layered on top. It complies with JIS X6319-4, and NFC Forum's Type 3 Tag spec — the tag class your phone's reader mode recognizes — is compatible with that same JIS standard. Every FeliCa transaction generates a fresh encryption key during mutual authentication, which is why a Suica card can't simply be copied by holding two phones together. And unlike a battery-powered device, a FeliCa card has no power source of its own — it draws power from the reader's field only for the moment of the tap. Phone-side systems like host card emulation achieve something similar without a dedicated secure chip, though FeliCa relies on Sony's own SE hardware instead.
Where you'll see it
FeliCa is the backbone of Japan's transit and e-money infrastructure. JR East's Suica, the Tokyo-area PASMO card, and JR West's ICOCA all run on it, alongside e-money brands like Edy, nanaco, and WAON. On phones, the same tech shows up as Osaifu-Keitai ("wallet phone") — launched by NTT DoCoMo in July 2004 and later adopted by au and SoftBank, letting one handset carry multiple FeliCa-based cards at once.
Apple's involvement started narrowly. FeliCa support first landed on Japan-market iPhone 7 and Apple Watch Series 2 units in October 2016, tied to nearly two million FeliCa terminals already installed nationwide — part of the same underlying NFC framework covered in our guide to how Apple Pay and Google Pay use NFC. From the iPhone 8 and iPhone X onward, Apple builds "Global FeliCa" hardware into every unit worldwide, not just Japan-market phones. FeliCa isn't only a Japan story, either — Hong Kong's Octopus card and Singapore's EZ-Link both run on it too.
Tips, gotchas, and a quick how-to with NFCore
Here's the practical limit: NFCore can detect and read the public NFC-F identifiers Android and iOS expose from a FeliCa card or NFC Forum Type 3 Tag — but the balance, ride history, and payment data on cards like Suica live behind Sony's secure element, encrypted and inaccessible to third-party apps by design. That's not a gap in NFCore; it's the same security model that keeps a lost Suica card from being drained by whoever picks it up.
Open NFCore's Tag Inspector near any NFC-F tag or FeliCa-compatible card to see this in action. On Android, NFCore reads it through the platform's full NFC-F stack. On iOS, Core NFC detects Type 3 Tags, but Apple limits deeper reader-mode access on FeliCa-branded cards, so results may differ by platform.
Frequently Asked Questions
Is FeliCa the same as NFC?
FeliCa is one of the technologies NFC incorporates, not a separate wireless standard. Within the NFC family it's called NFC-F (or Type F), alongside NFC-A and NFC-B, all sharing the same 13.56 MHz band.
Can my iPhone read FeliCa tags?
iPhone 8 and later ship with "Global FeliCa" hardware worldwide, so Core NFC can read NFC-F tags. Earlier FeliCa support (iPhone 7, Apple Watch Series 2) was limited to Japan-market units.
Why does Japan use FeliCa instead of standard NFC-A cards?
FeliCa predates the unified NFC standard and was built by Sony for fast, high-throughput transit gates — its quick handshake and dynamically generated authentication key suited Japan's high-volume rail networks better than early Type A/B alternatives.
Does NFCore support reading FeliCa cards like Suica?
NFCore can read the publicly broadcast NFC-F identifiers Android and iOS expose, but Suica, PASMO, and similar transit cards encrypt their balance and ride data behind Sony's secure element — that data isn't accessible to third-party apps by design.
Conclusion
FeliCa is Sony's contactless card technology, known inside the NFC standard as NFC-F — the system quietly running every Suica tap, Osaifu-Keitai payment, and Global FeliCa transaction on a modern iPhone. The next time your phone taps a reader in Tokyo, that's NFC-F at work. Open NFCore's Tag Inspector to see exactly which NFC technology you just used, and how much of a Type 3 Tag is actually visible to your phone versus locked away in Sony's secure element.
