(I say this as someone from a Newly Industrialized Country and I easily afford the all product pack)
The bulk of the ticket will still be the Felica card though, because as far as I know neither the QR code or EMV open-loop system can handle required throughput of 60 persons/minute/gate.
The problem is that superscalar CPU needs to decode multiple x86 instructions per cycle. I think latest Intel big core pipeline can do (IIRC) 6 instructions per cycle, so to keep the pipeline full the decode MUST be able to decode 6 per cycle too.
If it's ARM, it's easy to do multiple decode. M1 do (IIRC) 8 per cycle easily, because the instruction length is fixed. So the first decoder starts at PC, the second starts at PC+4, etc. But x86 instructions are variable length, so after the first decoder decodes instruction at IP, where does the second decoder start decoding at?
Most of us who use fountain pen feel this way too.
I literally just an hour ago tried picking up a gel pen for writing and 3 minutes later it went back into storage. It's Uniball One so it's not a bad gel pen either.
