Japan's IC cards are weird and wonderful

日本的 IC 卡系統奇妙且獨特
https://arbitraryurl.example/japans-ic-cards-are-weird-and-wonderful

📌 Summary:
文章介紹日本 IC 卡系統的獨特之處,尤其是以 Sony 開發的 FeliCa 技術為核心,與西方普遍使用的 MIFARE 及 EMV NFC 技術形成鮮明對比。FeliCa 不僅在速度上遠優於西方標準,能迅速通過站閘,且透過卡內儲存價值與交易紀錄,加速交易流程,避免因依賴伺服器溝通而拖慢速度。作者分享了 FeliCa 技術的歷史背景,從香港的八達通卡開始推廣,後來被日本 JR 東日本的 Suica 卡及樂天 Edy 卡採用,並延伸至亞洲多國。文中也探討 Osaifu-Keitai(手機電子錢包系統)與 FeliCa 的關係,說明現代手機需搭載 NFC-F 支援並具備安全元件(Secure Element)方能模擬 IC 卡,且 Android 與 Apple 手機在此功能上的差異。最後,文章分別評估了 FeliCa 卡的安全性,指出其基於硬體加密與單卡專屬密鑰設計,對複製及重播攻擊具高度抵抗力,且監控系統能透過熱點名單控管異常,提升整體防護。文末作者對未來可能的研究方向與愛好專案提出構想,期望深入軟硬體整合及提升讀寫速度。

🎯 Key Points:
→ NFC 基礎知識與類型:
  NFC 使用 13.56 MHz 無線通訊,根據 ISO/IEC 14443 規範分為多種標準。
  EMV 為歐洲聯合 Mastercard 與 Visa 的支付標準,多用於信用卡及行動支付。
  MIFARE 系列卡片多用於門禁與公共交通,早期 MIFARE Classic 安全性差,易被複製。

→ FeliCa 技術與應用:
  Sony 1988 年開發的 NFC-F 標準,早於 MIFARE(1994 年),主要用於日本及亞洲公共交通。
  交易速度高達 424 kbps,交易時僅卡與讀卡機互動無需外部伺服器,提高通過效率。
  卡片自身儲存餘額與交易紀錄,並具備多卡衝突迴避功能,避免同時讀取錯亂。

→ Osaifu-Keitai 與手機模擬 IC 卡:
  Osaifu-Keitai 為日本 NTT Docomo 發展的手機電子錢包系統,利用手機內 Secure Element 儲存密鑰。
  所有現代支援 NFC 的手機均含 NFC-F,但並非所有設備都具 Osaifu-Keitai 功能,主要與安全元件密鑰與授權有關。
  Apple 裝置全線支援 Osaifu-Keitai 功能,Android 多依產地(日本或全球版)及授權情況有所不同。

→ 安全性評估:
  FeliCa 採用專有加密,卡內每張皆有獨立密鑰,防止卡片複製與重播攻擊。
  雖然加密細節不公開,但公開資料顯示成功攻擊稀少且大多被系統及時偵測。
  讀卡終端也設定有熱點名單用於封鎖異常卡片,並將交易紀錄回傳中央,確保系統完整性。
  離線終端(如販賣機)因未即時上傳紀錄,可能成為防護盲點。

→ 未來展望:
  作者計劃自行打造微型車站軟硬體系統,模擬整套票務運作,當作娛樂與學習專案。
  希望能進一步瞭解 FeliCa 讀寫速度背後物理特性,探索優化 NFC 反應時間的可能性。

🎮 Hack NFC. Emulate transit. Play arcade.

We're building a userland Linux implementation of Android’s NFC-F (FeliCa) Host Card Emulation—so your Linux device can act like a real Japanese contactless card!

That means:
- Emulate Suica/PASMO-style transit cards
🛤️
- Log into arcade games:
-
SEGA Performai (maimai, CHUNITHM, O.N.G.E.K.I) via Aime
-
Konami e-Amusement (beatmania IIDX, GuitarFreaks, DrumMania, DDR, Sound Voltex, DanceRush Stardom)
-
Bandai Namco BaNaPassport titles (Taiko no Tatsujin, Wangan Midnight Maximum Tune)
-
SEGA's Initial D Arcade Stage series

We're looking for reverse engineers, Linux hackers, and Arcade fans to help bring Secure NFC emulation to Linux. Let’s make your laptop or Linux phone your next arcade pass!

Looking for aspiring Linux hardware and software hackers to work on NFC-F/FeliCa (Secure NFC) support in Linux! We're interested!

Imagine Linux emulating transit cards— also logging into SEGA (Aime), Namco (BaNaPassPort), Konami (e-Amusement) arcade games!

Join us
@hq and let's turn Linux phones into transit (or arcade) cards! Let's ride the train, on Linux! #nfc #nfcf #felica #linux #hardwarehacking

@rampagerslife I've seen some #pasmo & #suica (#FeliCa) #RFID cards with that as print-on.

@unseenjapan I think #pasmo and #Suica (as well as other #FeliCa-based systems like #Octopus) are really super convenient in terms of Pre-#NFC #RFIC-based #cashless #payment systems, to the point that #vPay, #PayPass and #girocard (as well as the flopped #GeldKarte) are just bad imitations of those!

Anyone knows if the OnePlus 11 phone supports Japanese Suica (FeliCa) card-app (not sure what the right term is) ? If so, which app is the "best" ?

@unseenjapan I mean, #pasmo and #suica have been around.even before the millenium to the point that even the 1st #iPhone in #Japan supported these (and other #RFID / #NFC-based payments based on #FeliCa)...

Problem is that their business model should not exist to begin with.

#CreditCards suck - period!
youtube.com/watch?v=wqhGyLP9Q0

#SEPA wire transfers and #ec / #giropay work way better and have way higher adoption and acceptance in #Germany due to lower fees and not requiring someone to have yet another contract with yet another value-removing middlemen!

That being said, #prepaid #cashless payment systems that ain't that well integrated died out for that reason, like #GeldKarte, which was a bankless prepaid cash card [similar to #Pasmo and #Suica, but instead of using Sony's #FeliCa #RFID tech it used #Chip + #PIN tech] that suffered from the fact that it required people to manually top it up and so it was rarely used by few people - like a #Payphone-Card...

Case in point: #Cash just works and we should fight for it's continued existance unless we can abolish #capitalism instead, then we should do that instead!!!

I was browsing through the Kamerastore website recently and came across this wonderful little camera, the Vredeborch Felica. It reminded me of the Agfa Clack, my weapon of choice for the #FrugalFilmProject, so I just had to have it.

Like most of the items I order from Kamerastore it was in the ‘Not Passed’ category and was described as being heavily used and with a hazy lens. Despite this, I placed my order and after a few days a nicely packed camera arrived. On receipt I was surprised at the condition of the Felica. For a camera made in the 1950s it was in lovely condition. Yes, the metalwork was a little scratched here and there, and the lock on the bottom was a little loose, but I couldn’t really see any haze in the lens, and after a little clean it was shining. The grey leatherette looked really good after a quick clean.

The Vredeborch Felica is a 120 film camera made in West Germany in the late 1950s. It has zone focussing, two shutter speeds, and bulb mode, and two aperture settings. There’s also a large yellow filter that flips into place behind the single lens to increase contrast. On the top of the Camera is a shutter button, which with gentle pressure fires and cocks the shutter for the next exposure. Also on the top of the Camera is a cold shoe,  to attach a flash which connects to a Flash PC socket on the lens barrel, and a wind-on knob.

It resembles a slightly more compact Agfa Clack, and I was wondering if it was possible to flip the lens, like in the Clack. However, the whole lens unit is sealed and I could not see how to access it. That said, now that I have used it I’m perfectly happy to leave it alone.

As I was planning to go to Aveiro for #HolgaWeek, I thought it was a perfect opportunity to test the Felica too. Of course, the first image I took was of my favourite tree and well across the road from our house. In fact, I took three photos, with red, green and blue filters to make a trichrome. The remainder of the film I used around Aveiro.

Upon receiving the image files from Forever Blue I was delighted with the results. I was concerned that I was going to get some camera shake with the 1/50s shutter speed, but a gentle press on the shutter button gave perfectly sharp images, and I nailed the zone focussing of the single meniscus lens. I should add that I taped up the camera to make sure there were no light leaks, and also taped shut the lock on the bottom so the camera stayed shut.

The Fomapan Retro film behaved perfectly, there was no sign of a ‘fat’ roll like in the Clack and the contrast of the images was lovely. On the whole the Vredeborch Felica is a wonderful little camera and I’m really glad that I took the plunge and ordered it. 

Outtake: When I received the image files, the numbering of the image files was reversed, so file number ‘0001’ was the last image on the roll and ‘0012’ was the first image. However, when I created the trichrome I forgot this and instead of using images 12, 11, and 10 for the red, green and blue layers, respectively, I used them in 10, 11 and 12. The results were … interesting. Someone on social media thought it reminded them of Lomochrome Turquoise film, and I was quite amused by that, and somewhat intrigued.

“然而,他說,Apple在110年通知,總公司評估後決定先以韓國為合作對象,但雙方仍持續交流至今,其中著力最深的就是卡片規格,因為Apple認為悠遊卡現在採用的規格安全性太低,悠遊卡公司則試圖努力說服Apple接受新式超級悠遊卡(SuperCard)的規格。”

lol… but SuperCard just emulates MIFARE Classic as well 🙃

is being a bit dishonest here. The problem is they’re using old tech that isn’t deemed secure enough by today’s standards. If they’re upgrading gates, why not switch to using cards instead, which could be supported in too 😌

それはそうと、スマートフォンでの #FeliCa 決済の基盤となっている #おサイフケータイ というプラットフォームはゴミカスなので、はよApple Pay相当の利便性が欲しい

2022-11-12

一方で #楽天ペイ を推している楽天が #FeliCa を採用した #Edy を無視してNFC TypeA/Bに秋波を送るのはある意味当然で、どう物販決済などでFeliCaを振興していくか、という課題は残るだろう

2022-11-12

#JR東日本#QRコード乗車券 を導入するから #Suica が使う#FeliCa がオワコンとする向きがあるけど、電車区間の大量の乗客を捌くにはSuicaは不可欠なので、コストメリットが無くなろうとも無くせない存在であることは確実では?

#楽天モバイル から #eSIM 内蔵で、Rakuten Watchとか出ないんですか? 当然 #FeliCa 搭載で

三菱UFJ銀行「MUFG Wallet」開始。Visaのタッチ決済対応ウォレットアプリ
watch.impress.co.jp/docs/news/

また乱立かーとしか思ってなかったですが、

>ウォレット内の残高をVisaのタッチ決済対応加盟店で利用できるアプリで、Androidのみでの提供。NFC搭載のAndroid 6.0以降のスマートフォンで対応する。

#FeliCa でなく #NFC 搭載 #Android で行けるんですねこれ。ほほう。
手持ちのFeliCa非対応のEssentialPhoneとNexux5Xでも行けるのでは?🤔

>今後は、三菱UFJ-VISAデビット以外のカードなどにも順次対応予定。「将来的には財布中のカードをアプリに登録できるWalletサービスを目指す」という。

さっさと対応カードを増やすのです。
