125 Kz
RFID at 125 kHz
RFID (Radio-Frequency Identification) operating at 125 kHz is a type of low-frequency RFID system. The 125 kHz frequency band is used for proximity identification where read distances are on the order of a few centimeters up to a meter.
Key Characteristics
Frequency: Typically 125 kHz or 134.2 kHz for Low Frequency (LF) RFID.
Read Range: A few centimeters to approximately one meter.
Data Transfer Rate: Lower compared to higher frequency systems.
Applications: Animal identification, access control, and asset tracking.
How It Works
RFID systems consist of two main components: a tag and a reader. The reader emits a signal that activates the tag, which then transmits its data back to the reader.
Advantages and Disadvantages
Advantages:
Good penetration through materials such as water and body tissues.
Relatively simple and inexpensive to manufacture.
Disadvantages:
Slower data read rates.
Shorter read range necessitating close proximity to the reader.

Potential Attacks by Flipper Zero on 125 kHz RFID Systems
Cloning RFID Tags
Cloning: Flipper Zero can capture and replicate the signal of a 125 kHz RFID tag, allowing unauthorized access by duplicating IDs.
Usage:
Scan the RFID tag with Flipper Zero.
Store the tag's data on the Flipper Zero device.
Emulate the tag or write its data to a writable RFID card.
