Visa has announced new global best practices for data field encryption, also known as end-to-end encryption - a much-discussed solution in the wake of the
Heartland Payment Systems breach. Announced by the global credit card company on Monday, these best practices are designed to further the payment industry's efforts to develop a common, open standard while providing guidance to encryption vendors and early adopters. Data field encryption protects card information from the swipe to the acquirer processor with no need for the merchant to process or transmit card data in the "clear."
