In October 2009, Visa published the Visa Best Practices for Data Field Encryption to promote the proper encryption of sensitive card data that is transmitted, processed or stored by stakeholders throughout the payment system. As part of these best practices, Visa recommended that entities use tokens (such as a transaction ID or a surrogate value) to replace the Primary Account Number (PAN) for use in payment-related and ancillary business functions. Tokenization can be implemented in isolation or in concert with data field encryption to help merchants eliminate the need to store sensitive cardholder data after authorization. Entities that properly implement and execute a tokenization process to support their payment functions may be able to reduce the scope, risks and costs associated with ongoing compliance with the Payment Card Industry Data Security Standards (PCI DSS).
To reinforce its commitment to protecting consumers, merchants, and the overall payment system, Visa is pursuing a global security objective that will enable merchants to eliminate the storage of full PAN and expiration date information from their payment systems when not needed for specific business reasons. To ensure consistency in PAN truncation methods, Visa has developed a list of best practices to be used until any new global rules go into effect.

The inclusion of Corporate Franchise Servicer agents in the Visa Third Party Agent Program will help ensure that Corporate Franchise Servicer agents protect card data by at a minimum complying with the Payment Card Industry Data Security Standards (PCI DSS).
It is common practice for some card issuers to print the full PAN on each page of a cardholder’s billing statement; however, Visa strongly recommends that, as a “best practice,” issuers truncate or eliminate the printing of the cardholder PAN on billing statements and other cardholder communications.
