Today I learned that Japanese smartphones have a icon on the back of the phone telling you exactly where the NFC reader is! Wish we had this in the US (or the rest of the world for that matter) 
I tried it on two different smartphones from Japan and they both had that icon and they both read my NExT PERFECT when I placed it there!
This is a Xiaomi 11T Pro from Japan:
And this is how it looks in other countries:
Hmm⌠it might just be that phone for whatever reason⌠@RyuuzakiJulio is actively selling implants there as VivoKey Japan and Iâm pretty sure placement / finding the âsweet spotâ is still an issue for Android phones. Still, fuckin cool⌠would be great if all phones did that.
My friendâs coworker had the same icon on his Sony Xperia.
I asked him to check all his friends phones when he gets back to Japan.
I can confirm Japanese iPhones donât have the icon, but iPhones donât really count. If Apple ever put a mark on the iPhone, the ghost of Steve Jobs would rise up and kill Tim Cook and all the other Apple executives 
According to Chat-GPT (prompted in Japanese and translated to English)
In Japan, phones often have a visible âNâ mark or sticker on the back showing exactly where the NFC antenna is. Thatâs because NFC here isnât just for mobile payments â itâs been used for years for things like transit cards (Suica, Pasmo) and quick tap payments in stores.
The system started back in the mid-2000s with âOsaifu-Keitaiâ (mobile wallets) using FeliCa, which works like a contactless transit card. People needed to know exactly where to tap so it works instantly â especially at train station gates or in busy checkout lines. If you miss the right spot, you slow everyone down.
By around 2011â2012, when NFC for credit cards and Android Pay became common, Japanese models kept that tradition and made the NFC location really obvious. Even overseas phone models sold in Japan often get the extra marking.
In the US, NFC never had the same split-second requirement for train gates, so phone makers didnât bother making the spot visible â people just tap somewhere near the back and it works fine. Thatâs why the âNâ mark looks unusual to you.
