Maybe it’s because I don’t live in a big city, but it is still quite rare to spot other Monzo users when out and about.
Only this week, during a short city break, I spotted a grand total of 1 Monzo card at the bar in the airport.
We have just recently started to take contactless payments at work (local public service) and I would say that not counting the “mainstream” banks, the cards we see most are:
Whilst I can understand Revolut, with their huge customer numbers, Starling and Monese are a surprise and I would have thought Monzo would have been more visible, given their relative popularity too.
I know there are many people who use Apple/Google/Samsung pay, so that may skew the number of actual cards seen.
