Global NFC FitBit Sense and Versa 3

Who would have thought that team FitBit would beat team Pixel to the market with global NFC devices? That is what happened with the release of FitBit Sense and Versa 3, any device bought in any country can add and use Suica. FitBit Charge 4 was the first device to support Suica but only for certain Japanese models. This means that Android users without global NFC can now add it with FitBit Sense and Versa 3. FitBit was up to the global NFC challenge all along. Going forward FitBit needs to expand Japan payment options to include iD, QUICPay, Waon, Nanaco, Mobile PASMO and NFC Pay.

There is one catch: the device must be registered and the IP address must be in Japan to use Suica. It sounds like Mobile Suica lite is being used. Hopefully the same approach can be employed to launch Octopus on FitBit devices in Hong Kong, there are users there who would appreciate it.

Mobile Suica Lite

With the proliferation of wearables JR East has been busy adding new devices to Mobile Suica. A timeline:

  • 2006: Mobile Suica for Osaifu Keitai
  • 2016: Apple Pay Suica for iPhone and Apple Watch
  • 2018: Google Pay Suica for Android Osaifu Keitai
  • 2020: Garmin Pay Suica, wena 3 Suica
  • 2021: Fitbit Pay Suica

The first hardware standard for Mobile Suica was Osaifu Keitai first on Symbian feature phones in 2006 followed by Android in 2013. This is the basic FeliCa chip in phone approach.

Apple Pay Suica in 2016 brought a new hardware model: a Apple custom embedded secure element (eSE) with licensed Mobile FeliCa for iPhone and Apple Watch. Pixel 3 and later models employ a somewhat similar arrangement using NXP multi-protocol NFC controllers with preinstalled Mobile FeliCa but Osaifu Keitai software is only activated on Japanese Pixel models.

A shortcoming of the Osaifu Keitai standard is that it only works on Osaifu Keitai ready Android smartphones. In 2016 Google released the HCE-F specification for Android 7.0. Japanese tech media at the time assumed HCE-F would become widespread for delivering FeliCa services to low-end Android devices without Osaifu Keitai support but that didn’t happen. As FeliCa Dude points out, “HCE-F is not useful for emulating existing FeliCa cards because the API has been needlessly crippled.” The HCE strategy is questionable and comes with security risks. In the pre-Apple Pay, pre-Google Pay era it seemed like a viable path, but things haven’t panned out in the embedded secure element era of today.

So how does JR East host Gamin Pay Suica, wena 3 Suica and Fitbit Charge 4 Suica wearables without Osaifu Keitai? The answer is what I call Mobile Suica Lite, a prepackaged service that supports some basic Mobile Suica features but has limitations:

  • New digital issue of regular non-registered Suica cards only, no transfer of plastic Suica cards.
  • No transfer of Suica to new devices
  • Deleting Suica from the device comes with a SF balance refund option (¥200 service fee + transfer to a Japanese bank account) but once the card is deleted it is gone forever.
  • No supplemental Suica services
  • Google Pay recharge backend

For wearables in the COVID era with teleworking and less reliance on commuter passes, Mobile Suica Lite is surprisingly useful despite the limitations. If you migrate to a new wearable simply run the SF balance down to zero, delete the old card, then issue a new digital card on the new device.

How exactly is JR East doing this? We know for certain that it is not Osaifu Keitai or HCE-F. My theory is we are witnessing Mobile FeliCa Cloud in action. According to FeliCa Networks Mobile FeliCa Cloud is:

…a service platform that connects NFC FeliCa Devices with Mobile FeliCa services. With Mobile FeliCa Cloud, the seamless provision of Mobile FeliCa services becomes possible regardless of OS or platform for smartphones and wearable devices…

What is a ‘NFC FeliCa’ device exactly? All NFC certified devices must support NFC-A, NFC-B and NFC-F. Any Global Platform certified secure element on a device also supports Mobile FeliCa. I suspect that any manufacturer with NFC and Global Platform certifications can pick Mobile FeliCa Cloud services à la cart from FeliCa Networks: i.e. I’ll have a Mobile Suica lite with a side order of Rakuten Edy but hold the iD.

Mobile FeliCa Cloud doesn’t come with all the Osaifu Keitai bells and whistles, but it also streamlines and eliminates Osaifu Keitai support headaches with prepackaged services. A Mobile FeliCa lite option for lite wearables…I hope we see more of it on more devices with more services.

Suica comes to Fitbit Charge 4 on March 4 (updated)

UPDATE: Mobile Suica for Fitbit Charge 4 launches March 4

JR East announced Suica on FitBit Charge 4 service starting in March 4, just before the March 13 Suica transit tweaks go into effect. It’s exactly the same Mobile FeliCa Cloud powered package used for Garmin Pay Suica and wena Suica services that launched in 2020, with the same limitations: no plastic card transfers, no commuter pass support, credit card recharge limited to Google Pay.

These limitations are not deal breakers. With many company people teleworking during the COVID crisis there is less need for commuter passes. For users who want the complete Mobile Suica service on a wearable, Apple Watch is still the only game in town. Nevertheless this is a welcome addition for many Android users in Japan.

The Fitbit JP page has a few Suica details. It appears to be a Japan model only device, not a global NFC device…and only the black model support Suica. It’s too early to tell if this development has anything to do with Google finally closing the Fitbit acquisition or if this is the first step towards supporting major FeliCa payment services like iD, QUICPay, Waon, etc. Robust seamless global NFC support across Pixel and Fitbit devices from anywhere would be the first real challenge to Apple Pay Suica on iPhone and Apple Watch.
