## Payment by saved card

When passing the project\_client\_id parameter, the user will be able to save the card on the payment form. To save the card, the user on the payment form should click "save card" and make a successful payment on this card. \
\
For further payments on the saved card it is necessary to pass the parameter project\_client\_id. \
\
The peculiarity of payment by saved card is the absence of 3DS user authentication, which significantly speeds up and simplifies the payment process.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.tarlanpayments.kz/eng/acquiring/interaction-with-the-payment-method/initiating-funds-receipts.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.
