Smells like Super Suica: Sony unveils next generation FeliCa

Sony announced the next generation FeliCa chip on September 8. Next generation FeliCa was mentioned in the September 2018 next generation Suica, aka Super Suica, press release. This is the first glimpse into some of the new FeliCa features that Super Suica will use. The Japanese and English press released highlight different feature sets. A basic rundown:

  • Extended Overlap Service: different service providers can share additional services, while making the most of existing systems.
  • Value-Limited Purse Service: purse data can be set as a negative numerical value, and enables “Upper Limit Value” and “Lower Limit Value” to be specified.
  • FeliCa Secure ID: on the surface this cloud based service sounds exactly like the digital car key feature Sony and NTT Docomo demoed at the Docomo Open House back in January and exactly like Apple Pay Car Key sharing. Dare I say there seems to be more web service functionality that might relate to the NFC Tag Maas Suica hinted at by AquaBit Spirals CEO Tomohiro Hagiwara.
  • Additional Security Options and higher performance: state of the art AES encryption method with high assurance EAL6+. Integrity protection option for ‘cost-balanced system solution use cases where higher priority is given to high-speed transactions while meeting the required security needs’ and last but not least higher transaction speeds. The new chip also complies with Public Transportation IC Card Protection Profile (PTPP).

The new hardware chip is NFC Forum Type 3 Tag compliant and works with NFC Forum certified devices.

As I explained previously, one big aim of next generation Suica is sharing resources and services to reduce costs. Right off the bat Extended Overlap Service looks exactly what Suica hopes to do: host other transit company commuter passes and reward points. The new FeliCa Japanese press release graph illustrates this, it almost looks like dual mode services in a single mode card. I think next generation Suica is going to leverage the shit out of it.

Another interesting feature is the Value-Limited Purse Service. Next generation Suica will hopefully get a stored value purse upgrade from the current ¥20,000 limit. I’m curious to find out if it uses the new feature for additional stored value services.

One big question is when does FeliCa Networks upgrade Mobile FeliCa with all these new features and when do licensed developers get the goods. Sony and NTT Docomo already demoed Android Osaifu Keitai smartphones using FeliCa Secure ID and digital car keys with Ultra Wideband ‘Touchless’ in January. I think it’s safe to assume licensees get new FeliCa chips and upgraded Mobile FeliCa at the same time.

This is just a cursory overview. I have fingers crossed that FeliCa Dude will post something to Reddit that will delight and enlighten us when he has the time. In the meantime we have Apple Pay PASMO coming down the pike very soon in what I hope is a preview of more to come in 2021.

UPDATE
FeliCa Dude has posted an excellent overview on Reddit covering the new features and what they mean for operators. More than ever I am convinced that the big new marquee features, Extended Overlap Service and Value-Limited Purse Service will be playing major roles in Super Suica.
