“In a move aimed in part at accommodating digital-only financial institutions, Visa Inc. on Saturday opened its ReadyLink prepaid top-up network for the first time to debit cards. “The expansion makes Visa ReadyLink available to all consumer and business debit cards. The service is optional and issuers need to opt-in,” notes a spokesman for the network. ReadyLink is Visa’s prepaid card load network for the U.S. market. It offers cash top-ups at more than 60,000 merchant locations. The addition of debit cards represents a rule change for the network.”
