Nobu Ringo (Nobu Apple) is my kind of Apple Pay Suica guy. His YouTube channel is filled with fun imaginative slightly dopey Apple Pay Suica exploits. Apple Pay Suica at McDonalds, KFC, Esso, parking meters and the extra, extra, extra spicy curry take home plate from Coco Curry House (complete with eating timer).
His latest exploit: recharging Apple Pay Suica while having a phone conversation. Tricky but it does work in case you are really on the run. And if you are wondering, he does it all on what appears to be iPhone 8 Plus not iPhone X. Good choice.
