# Using QR code

The use of QR codes is one way to facilitate and expedite transactions. There are two main categories of QR codes in Pix: Dynamic QR code and Static QR code. Let's understand the difference between them:

**Static QR Code:** The static QR code contains fixed information that does not change over time or transactions. It is useful for receiving payments for a specific amount and/or standardized information. For example, a merchant can generate a static QR code to receive payments for a fixed amount for a product or service. This QR code will maintain the same payment information, such as the Pix key and the amount, regardless of how many times it is scanned.

**Dynamic QR Code:** The dynamic QR code contains variable information that can be updated for each transaction. It is especially useful for transactions of different amounts or when specific information needs to be included for each payment. For instance: when making a purchase at an online store, the dynamic QR code can include the amount to be paid and other relevant details for that specific transaction. Each time the dynamic QR code is scanned, it can display a different value and unique details for that transaction.

## 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.aurixpay.com/guides/deposits/using-qr-code.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.
