 ===== Can you reactivate a supposedly disabled/invalid/dead card? =====
-So, the answer appears to be yes, at least according to reports on X, and now having tested it myself, my personal experience. What follows is a description of the process I used to "revive" a card that, on-paper, should have been invalid.
+So, the answer appears to be yes, at least according to reports on Twitter, and now having tested it myself, my personal experience. What follows is a description of the process I used to "revive" a card that, on-paper, should have been invalid.
 On February 19th, 2025, I successfully used a Suica that was last used on January 11th, 2008 (17 years, 1 month, and 8 days of inactivity). On February 20th, 2025, I tested it in the JR East Suica region and confirmed that the card is still valid, and I was able to transit and recharge using JR East Suica machines, and even successfully enabled タッチでGo! without a problem.

   * [[https://x.com/frozenpandaman/status/1749804271305207974|eli! 🐐]] reports: "apparently at JR Central ticket machines, any reciprocal-use transportation IC card *past its 10-year expiration* can be charged & reactivated forever 😱". Note that Eli's Tweet also includes screenshots in Japanese and English (translated) discussing how this is the result of the following alleged chain of events:
     * [[https://jr-central.co.jp/|JR Central]] supposedly abolished the 10-year expiry on their region-specific card, TOICA. TOICA cards supposedly have no expiration date on currently-issued cards. (**Note: my 2023 issued TOICA still says it's only valid for 10 years.**) Because of this, and because the cards are mutually operable between regions, you can "revive" a card in the JR Central region because the machines do not respect the expiry date, even though JR East's do.
+      * Eli pointed out (after publishing this article) that [[https://faq.jr-central.co.jp/71|JR Central says]]: "TOICAのカードや機器・システムは性能向上等のため随時更新を行っておりますが、長期間使用されていないカードについては､こうした機会がないために､最新のサービスレベルをご提供出来なくなる恐れがあります。このため､10年間ご利用がない場合には､失効することとさせて頂いておりますが、お客様の利便性を考慮し､機器・システムが対応できる期間は引き続きお使いいただける取扱いとしております｡（カード自体の不具合等により使用できない場合もございますので､その場合は駅係員にご相談ください。）". Additional documentation on the [[https://www.kotsu.city.nagoya.jp/jp/pc/INQ/TRP0000581.htm|manaca side of the house]] seems to indicate that cards don't expire, but may not be usable after 10 years.
 Anyways, the hypothesis I had was the following:
   * It is probably possible to reactivate an expired Suica in the TOICA region, if the card has been disused for over 10 years, and the card's disuse has NOT been recorded anywhere.
-    * I specifically speculate that presenting the card to JR East as expired will cause a cascading effect wherein JR East will not honor it. More and more of the Suica infrastructure is moving online. Supposedly, some Suica regions are already fully "cloud-based" and the role of the actual stored-fare on the card is becoming vague as each passing day progresses.

   * By charging the card and using it completely outside of the Suica region before the nightly maintenance period (when everything is supposedly reconciled on the actual server storage for Suica), I speculate that the validity of the card cannot be questioned.
   * At the very least, I suspect that since the card can only store limited data, if the card can be reactivated in any region, storing at least 20+ transactions on the card should make it unclear as to whether or not the card is still valid, because all recent activity is valid.

 I speculate that if the card "is disabled" it will likely stop working if used in the JR East region on all regions. I speculate that because it's a Suica, the only authority that can truly invalidate it is JR East, and by avoiding JR East's infrastructure, and then allowing the overnight maintenance period to reconcile the differences between the different regions, the card will be fully active.
-Before I consider the card "fully alive", I will continue testing it throughout the coming weeks. I think that if a card remains active for about 7 days, it likely will continue working indefinitely. Or at least, I don't see any good reason why it wouldn't.
+I now consider this card fully alive, with a recent trip on JR East having been completed on March 8th, 2025.
