- Minimal impact to payment processing systems. Merchants and acquirers ca adopt point-to-point encryption with ease because of the minimal impact to existing payment systems. To make the transition as easy as possible, Visa will also offer a "format preserving" option, enabling merchants to integrate point-to-point encryption using a 16-digit encrypted value with their current systems.
- Consistent, open encryption standard. Visa's encryption solution relies on the same Triple Data Encryption Standard (TDES) and Derived Unique Key per Transaction (DUKPT) key management that are used to encrypt PINs today. This provides a consistent framework for managing keys and minimizes the impact of merchant system updates.
- Multi-zone encryption. Visa's solution allows for encryption and decryption in multiple zones, providing merchants and acquirers flexibility in how to deploy encryption within their unique environments. Multi-zone encryption can facilitate routing to multiple endpoints, if the merchant is using multiple processors, consistent with how PIN encryption is managed today.
I think this is confirming the fact that -- despite all the PCI efforts -- P2PE (whether it is PCI approved or not) is the only technology that can provide a real protection for magnetic stripe payment cards.
