# 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.
