How Cards Work
Each agent gets a virtual Visa card issued by Modulr (EU EMI, regulated by Estonian FSA). Cards are usable anywhere Visa is accepted online.
Card Details
In sandbox mode, all cards use test number 4242 4242 4242 4242.
In live mode, real Visa cards are issued under your Modulr customer account.
Card credentials (PAN, CVV) are never exposed to the agent. Use the @ovra/pay SDK or CDP checkout to fill payment forms securely.
