I was able to order my coffee from a Costa machine using a QR code on the screen to link it up to my phone.Indeed not. But if you're obsessive about cleanliness to the point that using a TVM gives you great anxiety, such a phone does seem a very sensible purchase to make. It's not just TVMs where it can help - for example you can order from your phone on the fairly ubiquitous Costa Coffee machines, a facility that was introduced for COVID but is very likely to stay around.
Obviously reasonable adjustments must be made for disabilities, but it's also sensible to help yourself as well.
That same technology could be applied to TVM to avoid touching the screen.
