Visa Inc. has announced that it will for the first time make its Visa International and Regional Operating Regulations available publicly, effective May 15, 2008. According to Visa, the Operating Regulations, which will be available on Visa's corporate website at http://www.corporate.visa.com, are 'the set of rules which govern the participation of issuing and acquiring financial institutions in the Visa system.' Visa also said that 'to protect cardholder and merchant safety and the Visa system, Visa has omitted proprietary and competitive information, as well as certain details from the rules relating to the security of the network. For example, in the merchant rules, Visa has omitted authorization limits by country and processing codes which could aid fraudsters.'
