+# Reading RAW RFID data
+
+Flipper Zero has the option to read RAW data from 125 kHz cards that allows you to record the card's data and save it, similar to how a dictaphone records sound.
+
+To use this function, you need to activate the Debug mode on your Flipper Zero by doing the following:
+
+1. Go to **Main Menu** → **Settings** → **System**.
+
+2. Set **Debug** to **ON**.
+
+Once the Debug mode is activated on your Flipper Zero, you can read RAW data from 125 kHz RFID cards:
+
+1. Go to **Main Menu** → **125 kHz RFID** → **Extra Actions**.
+
+2. Select **RAW RFID** data and name the raw file.
+
+3. Read instructions and press **OK**.
+
+4. Apply the card to Flipper Zero's back.
+
+5. Once the reading is finished, press **OK**.
+
+Two files with data (with ASK and PSK modulations) will be saved in the `lfrfid` folder on the microSD card. Now, you can share it and the card's photo with developers by creating an issue on GitHub.
