Restrict access to cardholder data by business need-to-know

To ensure critical data can only be accessed by authorized personnel, systems and processes must be in place to limit access based on need-to-know and according to job responsibilities.

Need-to-know is when access rights are granted to only the least amount of data and privileges needed to perform a job.
