Card governance is the set of rules, approvals, and technical controls used to issue, limit, freeze, replace, and revoke payment cards. It covers both physical and virtual cards, including who can create them, what spending limits apply, where they can be used, and how quickly they can be disabled.
It matters because cards are a direct path to money movement. In cyber security, weak card governance can let a compromised account create new cards, raise limits, or keep using a stolen card after it should have been frozen. Strong governance reduces that risk with least-privilege permissions, step-up approval for sensitive actions, audit logs, and fast revocation workflows. In business payment platforms, administrators should treat card issuance and cancellation as security-critical operations, not just account settings.
