Re: While this is a real concern, it is only half the problem
The POS terminals over here all support all standards and you just hold the NFC card or smartphone over the terminal and it automatically selects the correct payment method.
I use 2 different debit cards (different banks) and the bank payment app on my Android smartphone. The POS just takes the payment. I've seen people using iPhones as well and they work just the same, the POS automatically selects the right protocol.
PIN is required in Germany for transactions over 25€ (I believe, because of CORONA, they upped this to 100€ temporarily) or after a certain number of PIN-less transactions at a level below the limit. With my debit card and my bank payment app, I usually have to enter the PIN every 2 weeks or so on average.
