# Low Frequency

Proxmark3 X can identify all 125KHz Tags by independent mode or LF Commands with Proxmark3 clients. Compared to Proxmark3 RDV4.01, Proxmark3 X does NOT support LF on the 134KHz tag. 

### LF Tag Clone by One-Click

Switch Mode 2 to use Independent LF Tag Cloner.

1. Click **LF Read Btn** to read the original tag.
2. Put ID Changeable LF Tag then click **LF Write Btn** to clone one.

### LF Tag Cloen by Commands

The commands can be run in [Proxmark3 Clients](/guides/use-proxmark3-x-on-windows.md#gui-functions), [Proxmark3 Command Line Tool](/guides/use-proxmark3-x-on-macos-linux.md#connect-proxmark3-x), and [RFID Tools App](/guides/use-proxmark3-x-on-android.md#rfid-tools) with Bluetooth or USB connection.

# Agent Instructions
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://proxmark3x.mtoolstec.com/commands/low-frequency.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.
