Reading 125 kHz RFID cards
Flipper Zero allows you to read, save, and emulate 125 kHz RFID cards. A 125 kHz RFID card is a transponder that stores a unique identification number. When scanned with a reader, a 125 kHz card transmits its ID number. If the card has the supported protocol, Flipper Zero can read and save the ID number.
On this page, you’ll learn how to read, save, and emulate 125 kHz RFID cards with your Flipper Zero.

How to read 125 kHz cards
To read and save the 125 kHz card’s data, do the following:
Go to Main Menu -> 125 kHz RFID.
Press Read, then hold the card near your Flipper Zero’s back.
While reading, Flipper Zero switches between ASK and PSK codings every three seconds to read data from the 125 kHz RFID card.
Once the reading is finished, you’ll see the card’s data on the screen.
To save the card, go to More -> Save.
Name the card, then press Save.
If reading failed
- The card might be using NFC technology. -> Read the card with the NFC application.
- Flipper Zero switches codings every three seconds. Some cards might not be read because it can require up to 10 seconds to read data. -> Read the card with a preselected ASK or PSK coding.
Reading with a preselected coding
Flipper Zero allows you to read 125 kHz RFID cards with a preselected ASK or PSK coding.
To read and save the 125 kHz card’s data with a preselected coding, do the following:
Go to Main Menu -> 125 kHz RFID -> Extra Actions.
Select Read ASK or Read PSK.
Hold the card near your Flipper Zero’s back.
After reading, go to More -> Save.
Name the card, then press Save.
Emulating 125 kHz RFID cards
Flipper Zero can emulate saved 125 kHz RFID cards by doing the following:
Go to Main Menu -> 125 kHz RFID -> Saved.
Select the card you want to emulate, then press Emulate.
Hold your Flipper Zero near the reader, the device’s back facing the reader.
