The Reserve Bank of India (RBI) on March 6, 2024, said card issuers should not enter into any arrangement with card networks that restrain them from availing the services of other card networks. The card issuers should provide an option to their eligible customers to choose from multiple card networks at the time of issue, the RBI said. For the existing cardholders, this option may be provided at the time of the next renewal, the RBI added. These rules are effective six months from the date of this circular.
