# Visa

Named alongside **Mastercard**, **American Express**, and **Discover** as a key player in the **Governance and Payments Layer** of the [[framework-agentic-tech-stack]]. These networks are tasked with building industrial-grade systems to **distinguish compliant AI agents from malicious bots**, preventing high-volume fraudulent purchases and **prompt-injection attacks**.

*Enrichment note (canonical: visa.com):* Visa is referenced in protocol literature as part of the **payment and trust** layer, responsible for fraud detection and agent-authorization frameworks. Peer networks are advancing agent-payment initiatives (e.g., Mastercard's Agent Pay) and delegated-payment / tokenized-credential trust protocols.
