Basis Theory offers a programmable PCI Level 1-compliant token vault for merchants, fintechs, AI platforms, and SaaS companies to create engaging commerce flows, connect with any partner, effortlessly manage compliance, and keep control of payments data.

Basis Theory's partnership with Nuvei lets merchants process payments through Nuvei without ever touching raw card data. Cardholder information is collected and stored in Basis Theory's PCI Level 1 vault, then securely detokenized and forwarded to Nuvei via an ephemeral proxy at the moment of transaction. This keeps sensitive data out of merchant systems entirely, cutting PCI DSS scope and audit burden while allowing them to route payments to whichever processor they choose.
