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).
