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:

1

Go to Main Menu -> 125 kHz RFID.

2

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.

Flipper Zero switches codings every three seconds

Once the reading is finished, review the card&#;s data.

The captured data is displayed on the screen

&#;

4

To save the card, go to More -> Save.

5

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 might require up to 10 seconds to read data. ->

  Read the card with the preselected ASK or PSK coding

  .

&#;

Reading with a preselected coding

Flipper Zero allows you to read 125 kHz RFID cards with the preselected ASK or PSK coding.

To read and save the 125 kHz card&#;s data with a preselected coding, do the following:

1

Go to Main Menu -> 125 kHz RFID -> Extra Actions.

2

Select Read ASK or Read PSK.

3

Hold the card near your Flipper Zero&#;s back.

4

After reading, go to More -> Save.

5

Name the card, then press Save.

&#;

Emulating 125 kHz RFID cards

Flipper Zero can emulate saved 125 kHz RFID cards by doing the following:

1

Go to Main Menu -> 125 kHz RFID -> Saved.

2

Select the card you want to emulate, then press Emulate.

With Flipper Zero, you can emulate saved 125 kHz cards

&#;

3

Hold your Flipper Zero near the reader, the device&#;s back facing the reader.

While emulating the 125 kHz card, hold your Flipper Zero near the reader

For users who have just come into contact with it, RFID still has a bit of a technological feel. So today we're going to share the read and write range of RFID card readers. There are many types of RFID card readers, and the reading distance of different RFID card readers varies, and the RFID tags they read also have some correlation. The read and write range of RFID card readers is related to many factors. Below, we will discuss the working range of corresponding bands for different frequency bands.

Understanding RFID card readers

RFID card readers, also known as wireless radio frequency identification, automatically identify target objects and obtain relevant data through radio frequency identification signals without human intervention. They can identify high-speed moving objects and multiple RFID tags simultaneously, and operate quickly and conveniently. RFID card readers include fixed and handheld ones, and handheld RFID card readers include low frequency, high frequency, ultra-high frequency, etc.

Read and write range of RFID card readers

According to the frequency used to transmit information between electronic tags and readers, the common working frequencies of RFID systems are divided into four types: low frequency (LF), high frequency (HF), ultra-high frequency (UHF) and microwave, and the read and write ranges of each frequency are different.

LF RFID readers: Generally speaking, the reading distance of LF RFID tags is less than 10cm, and the reading distance is proportional to the size of the tag. LF RFID is mainly used in animal tracking and identification, access control management, car circulation management, POS systems, and other closed tracking systems.

HF RFID readers: HF RFID card readers have good anti-metal and liquid interference performance, and the reading distance is mostly within 1m. RF RFID tags have a faster transmission speed, but poorer anti-noise interference performance. Generally, they have read and write and anti-collision functions. High-frequency RFID is the most widely used in the field of RFID, such as certificates, cards, tickets (ID cards, public transport cards, tickets, etc.). Other applications include: traceability of individual items in the supply chain, access control management, libraries, pharmaceutical industry, smart shelves, etc.

UHF RFID readers: The biggest advantage of UHF RFID card readers is their long reading and writing distance, which is generally 3-5m and can reach up to 15m. However, due to poor resistance to metal and liquid, they are less used for identifying single items and are mainly used for tracking management of boxes or pallets, luggage tracking, asset management, theft prevention, etc.

RFID asset tags are a non-contact automatic identification technology. The RFID asset tag has a chip and an antenna, can repeatedly write data and be used multiple times, and can be read in batches, saving costs.
