I'll pass completely then, I don't mind credit cards too much since I like to get refunds.

I can't say my face isn't already in a bunch of countries databases in multiple countries; but I'll take the small loss to get in and out of the airport.

Despite not completely agreeing with the method, flying into Japan is so easy now. Literately just go get my passport sticker-ed, the more stickers the less questions, look in the camera, grab my luggage, check in a podium terminal and mark that you don't have pets and find out what exit to go through, and then walk out, another camera scans your face as you walk out. I would say the only thing that's slow is the baggage claim. Korea is really bad with this one.

I think eventually it will be inevitable. But I'll stick with cash as long as I can, not having something in your hand makes it really easy to overspend.
