Credit card transactions at the pay boxes are secure because pay boxes are PCI compliant. PCI is the Payment Card Industry (PCI) Security Standard for protecting data. It is a set of requirements designed to ensure that companies that process, store, or transmit credit card information maintain a secure environment.

When using a credit card at the pay box, credit card information is transmitted directly to the financial institution. CPM does not retain or store the data except for the last four digits of your credit card which is very similar to any other credit card transaction. Retaining the last four digits of the credit card enables CPM to provide better customer service in case there is a problem with the pay box and a refund is necessary.
