Your data flows to multiple parties beyond Visa itself, including your card issuer and the merchants you transact with, which multiplies privacy exposure and limits your control.
Visa collects extensive personal and transactional data, including purchase history and inferred preferences, and uses it for marketing, analytics, and sharing with financial partners and third parties. Consumers may not realize their payment data is being used for targeted advertising and profiling beyond basic transaction processing. You can opt out of targeted advertising and certain data sharing by visiting Visa's privacy choices page at https://www.visa.com/en-us/legal/privacy-policy.html.
