Fintech and neobank services cover digital current accounts, payment cards, money transfers, payment processing, savings and lending apps. Individuals use them for everyday banking and cross-border payments, and businesses for acquiring, invoicing and treasury. Providers include fully licensed banks, payment and e-money institutions, and apps that rely on a partner bank behind the scenes. PayPal and Wise are familiar reference points.
The sovereignty questions here are about who holds the money and who can see the flows. A transaction history reveals income, spending, relationships and location, and payment infrastructure is a critical dependency: if a provider freezes an account, changes terms or withdraws from a market, you can lose access to your funds or to payments. The licensing entity, the supervisor and the deposit protection scheme that applies depend on the country, so the brand name alone says little. Many apps also depend on a partner bank and on cloud providers, which adds further layers.
When choosing a European option, check which entity holds your account and whether it is a bank or an e-money institution, how client funds are safeguarded, and where the supervisor sits. Look at account portability, data export, SEPA support and how quickly you can move direct debits and salary to another provider.
