# RFID Cards
This is a feature supported by some hardware that allow users to use an RFID card to start rentals. It works because each RFID card has its own unique ID that can be read by supported hardware when in close proximity and then sent to our servers to identify the user and start a rental if possible.
Click + **Add RFID Card** at the upper right side. Add an RFID Card and fill in the Card ID field. You can also indicate the Card label field but this is optional and hit **Submit.**

## 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://documentation.movatic.co/admin-site/users/rfid-cards.md?ask=&goal=
```
`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.
