# PA-DSS Requirement 2.3

Render PAN unreadable anywhere it is stored (including data on portable digital media, backup media and in logs).

In Maitre’D, as soon as the system is configured for use with integrated card payments, it is automatically set so that all credit card payments will have the PAN and expiration date truncated without further configuration or user intervention.

Of course, other payment types using magnetic cards can be configured to show PANs in clear, like in-house receivable accounts or gift cards, loyalty programs, etc.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.maitredpos.com/maitred/maitred-pa-dss-implementation-guide/pa-dss-requirement-2.3.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
