About Keyno

Keyno provides a dynamic CVV2 code that hackers and scammers can’t use. Keyno replaces the static 3-digit CVV2 security code on the back of your current credit, debit or prepaid cards with a continually changing “dynamic” CVV2 code that hackers and scammers can’t capture and use. Keyno sends a new code every 4-12 hours to your smartphone, keeping your cards safe. This code is called a CVVkey.

The CVVKey Solution includes code delivery via a white label mobile app or SDK plugin, a customer service interface with reporting an API connection for new card issuance, performance optimizations, security features, and a roadmap of enhancements. CVVKey supports mixed BINs with AllIn / OptIn / OptOut card enrollment.
