Adyen is headquartered in Amsterdam, Netherlands, founded in 2006, and holds EU, UK, and US banking licences. Listed on Euronext Amsterdam and subject to Dutch and EU financial regulation, it processes payments from European data centres with full GDPR compliance.
Why choose Adyen over Square?
The decisive argument is data jurisdiction. Square is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes — the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Adyen removes that overhead. As a Netherlands-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors — health, public administration, finance — that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
