Suica cards (and transit express payments in other regions) work after iPhone batteries die for a few hours.
replyAre you saying that an iphone can be used as a Suica card even with a dead battery? Or just that a discrete card still works when your phone is dead?
replyiPhones still let you use certain contactless features (like Suica) even when the battery has "run out" (ie., the main OS has shut off). The reserve battery power is enough to run Suica, CarKey support, and FindMy.
