It’s the fact that it’s in near real time now, older techniques with older hardware would need much longer.

Interesting, my experience was in rural Georgia so could be regional?

I’d put money on it being the US.

I’m from the UK where chip and pin is required and contactless is nearly ubiquitous so when I was in the US recently I was baffled that a lot of places had me signing for things.

I can confirm that Neko still works flawlessly for me. I only use Mangadex so have never really been interested in the wider Tachiyomi space.
