Size: The keyfob typically measures around 34mm in diameter. This is a compact size, making it easy to attach to keychains or carry in pockets or bags.

LF (Low Frequency):

• This keyfob operates on Low Frequency (LF) RFID technology, which generally works within the 125 kHz frequency range.
• LF RFID tags are known for their relatively short read range (typically up to 10 cm), which is suitable for applications that don’t require long-range scanning, such as access control or proximity-based identification.

RFID Technology:

• Passive Tag: Most 34mm LF RFID tags are passive, meaning they don’t have a battery and instead get powered by the radio waves emitted from an RFID reader.
• Chip and Antenna: The tag contains a small chip and antenna, which store and transmit unique identification data when they come into range of an RFID reader.

Applications:

• Access Control: Commonly used in keyless entry systems for buildings, secure areas, or even vehicles.
• Identification: Used for employee identification, membership cards, or as part of a tracking system.
• Security: Used in alarm systems, asset tracking, or inventory management systems.

Durability: The keyfob is usually encased in a durable plastic housing to withstand daily wear and tear, and it is often waterproof, making it ideal for various environments.

Customization: The RFID chip inside the fob can be programmed with specific identification numbers or codes, making each keyfob unique to its user or application.
