Ask HN: Question regarding touching a stranger's phone

The question is: what is the solution to not having to touch a stranger's phone during certain situations? Is it implementing existing technology, or is it making something new?

1. This week, I ordered some alcohol off of doordash. The person handed me their phone and asked me to type my name and sign.

2. I was at pharmacy and they wanted updated information, so I handed them my phone and they typed it in.

There are 2 problems with this:

First of all, everyone uses their phone on the toilet and nobody cleans their phone as they should.

Second is that the phone is very personal and it is rather odd to hand that to a stranger.

How do you feel about sharing phones and everything associated with it? And why are there no articles about phone hygiene? Do you never hand your phone over or vice versa? Is this a problem or a non problem?
