What is an RFID keychain?
An RFID keychain is a small electronic tag with a built-in RFID chip and antenna, usually shaped like a keychain for easy carrying. RFID (Radio Frequency Identification) technology transmits data via radio waves. It is commonly used in access control systems (offices, residential communities, apartments), time and attendance systems, parking management, hotel room cards, gym membership identification, and campus card systems.
How do RFID keychains work?
When an RFID keychain approaches a reader:
The reader emits a radio frequency signal.
The chip inside the keychain is activated.
The chip sends its stored ID number to the reader.
The system verifies the identity and performs the corresponding operation (such as opening the door, checking in, etc.).
