Interesting, had a quick look, and apart from the implant & NFC fob,
its limited to support for 6 currencies, and its fairly limiting,it has the 4 main currencies, but has Bulgaria & Romania currencies, two places, less visited,
but nothing for Poland, Sweden, Norway,Denmark, Czech Republic, Australia, Japan, and many more.
Revolut has all of these.
“create up to 3 IBAN accounts for each of the 6 different currencies we support: EUR, GBP, USD, CHF, BGN, RON”
and there are plenty of fees, if you dig into the detail:
