13.56MHz RFID Tag with Keychain

13.56MHz RFID Tag with Keychain is a highly reliable, compact contactless token designed for seamless integration with modern access control and automated tracking systems. This durable transponder communicates over a High-Frequency (HF) wireless band, utilizing standard proximity protocols to interact effortlessly with compatible readers. Consequently, it eliminates the mechanical wear associated with traditional magnetic stripe or physical key systems. The lightweight ABS shell protects the internal copper antenna and silicon chip from everyday environmental hazards. Furthermore, the attached metal split ring permits easy fastening to personal keychains. Therefore, you can rapidly deploy this key fob to enhance security, track attendance, or streamline contactless ticketing processes across your facility.

Key Features:

• High-Frequency Performance: Operates at a precise 13.56MHz frequency to ensure rapid data transfer rates and robust anti-collision capabilities during scans.
• Rugged Waterproof Housing: Features a sealed ABS plastic casing that resists moisture, dust, and physical impacts during daily handling.
• Unique Identification: Contains a pre-programmed, unique identifier (UID) code to secure access points and eliminate the risk of duplication.
• Passive Power Supply: Operates entirely without batteries, drawing its necessary power directly from the electromagnetic field of the reader.
• Convenient Form Factor: Incorporates a strong iron split ring, making it highly portable and instantly accessible for users on the move.
