I would agree with Cameron, we found contactless to be extremely common, even in Sicily, except for cases where a person/company wanted cash probably for reasons, I think we all know.
I agree that once you get used to the train apps etc., it is easier. However, I wonder if anyone thinks about people advanced in years that just are unable to deal with the technology or even have a smartphone. My husband and I have four living parents. None of them have smart phones. There have already been tasks and transactions they needed to make that required smartphone technology. While none of them are independently traveling the world, they are relatively competent, but frequently have to rely on us for certain tasks, including making appointments and communicating with physicians. It makes them feel more dependent and diminishes them, which is not helpful to their well being.
