Any way to use おサイフケータイ without a JPhone?

Hello,

I am getting tired of having over 5 cards using NFC-Felica related stuff and have to keep them almost everyday.

I bought a OnePlus9 but it’s an international version, and it doesn’t support the Osaifu Ketai app. I was fine with just putting my wallet near the suica reader but i made a mistake of buying a new wallet which is RFID safe and now i need to take my card all the time. And you know how rushy people are here if i hesitate half a second at the train gate i get rear ended by 5 people.

So I am looking for alternative, not on phone, but on hardware.

I saw something from Docomo named おサイフジャケット which is exactly what I want, a small card that could support any type of card, but it looks like they discontinued it…

I was wondering if any of you guys know any external device that would for exemple

1) be like this おサイフジャケット
2) a small phone that would support Felica (I found this one http://akiba.jpn.org/?p=78852 and looks like a decent alternative. But looks a bit heavy for a little phone)
3) any “all in one” device that would connect or extend a phone/reader and store all the card on it
4) some NFC tags (so not card but little badge) that I could attach to a bag and pick easily.

Thanks
