Off topic: Venmo does not exist (?) in Europe land. What’s its appeal compared to PayPal or regular credit cards or even debit?
The Nordic countries all have bank-backed apps for instant transfers from a checking account indexed by phone numbers. It basically replaces every peer to peer transaction that would be cash in other countries (paying back a friend, buying something at a flea market, chipping in for a gift at the office...)
In Finland, bank-backed apps became less popular (and some even closed down), and MobilePay[1] became the most common way to send money around. I believe it's very similar to Venmo.
