Smart self-driving buses put into operation in Tianjin, China

My only issue is that
the palm scanner must get filled with various bacteria and microbes,like airport trays used in check in scanners.
It's not hygienic for people to put their palm on a scanner in public commute and then even eat with the same hand after procuring food in the bus. I would rather pay using cellphone rather than putting my palm on a public palm scanning device.

Yes, unless they have self cleaning device to clean the screen constantly, otherwise non contact recognition devices are preferred, that's the first time I see a palm scanner.

Not an issue actually, just like a door handle in a public building, a lot of people grab it... Serious diseases don't transmit this way. BTW, we don't use our hands to clean our azz:cheesy:
