>>51818022>, it's a piece of software that runs in the background detecting IC signals you fucking moronYou have no idea what you're talking about lmao. There's a lot of technical jargon here, so I'm not surprised someone like you doesn't understand it all, so let me break it down for you.
おサイフケータイ (osaifu-ketai) is a protocol that talks to the secure element on a device/card (traditionally, and still today, the FeliCa IC chip). When Suica was first released, the support for phones was a purely hardware implementation, once smartphones came around モバイルSuica was introduced to make supporting all the hundreds of manufactures easier, as this now implemented a web-based authentication system. That is why Apple is able to bypass the need for an actual FeliCa IC and use their own secure enclave. Google has the same potential, with their Titan M chip, but is too lazy to finish the implementation.
Both apps are ABSOLUTELY required, and the mobile suica app literally does not run without the service enabled. (picrel, the app literally prompting you to install the osaifu-ketai service from the playstore)
For someone who claims to have a lot of technical experience with this, you sure know very little about it.
