Pack of 50 Waterproof RFID Key Fobs (125 kHz, TK4100) - For Access Control and Management Equip your access control system economically and reliably with this pack of 50 passive ABS RFID key fobs. Designed for heavy-duty use, these robust and waterproof badges incorporate the standard TK4100 chip, a widely used reference for secure access management. Ideal for businesses, condominiums, schools, or hotels, this large pack allows you to equip a large number of users or maintain a strategic reserve of replacement badges. Technological Core: The TK4100 Chip, Market Standard 125 kHz Each key fob integrates a passive TK4100 RFID chip, operating on the standard low frequency of 125 kHz. This proven technology is recognized for its reliability and broad compatibility with thousands of existing badge readers, electronic locks, and access control systems worldwide. Each chip has a unique identifier (UID) engraved at the factory, ensuring individual traceability. These badges are read-only (non-rewritable): their UID cannot be changed, making them secure digital physical keys. Maximum Robustness and Durability with Waterproof ABS Housing: The chip is encapsulated in a compact, high-quality ABS housing, a plastic renowned for its resistance to impacts, UV rays, and everyday wear and tear. Ultrasonic welding of the two parts guarantees exceptional waterproofing (typically IP67 or equivalent), protecting the electronic chip from moisture, dust, splashes, and even temporary immersion. These badges are designed to last for years, even in harsh environments (warehouses, outdoors, shared pockets with keys). Extremely Simple to Use and Versatile Application Their use is intuitive: simply present them at close range (0 to 10 cm) in front of a compatible reader to trigger the programmed action (door opening, time tracking, parking access). They are perfect for: Physical access control: Office doors, gates, building lobbies, changing rooms. Time and attendance management: Time clocks for employees and students. Security: Access to restricted areas. Hospitality: As a replacement for or complement to magnetic cards for room locks (check compatibility). Logistics: Access management for warehouses or company vehicles. Economy Pack of 50 Units - Centralized Management Buying in packs of 50 is the most economical solution for equipping a team, a residence, or a school. This also allows you to have a stock of spare badges for new arrivals or to replace lost ones, without interrupting the system's operation. Integrated Ring and Compact Size Each key fob has a solid integrated metal ring, allowing it to be instantly attached to an existing key ring, so it's always within easy reach and difficult to misplace. Its small size (approximately 33 x 29 x 6 mm) makes it discreet and easy to carry. Important: Compatibility Check Before purchasing, it is essential to confirm that your access control/reading system is compatible with 125 kHz badges and the EM4100/TK4100 chip. These badges are NOT compatible with newer technologies such as 13.56 MHz (Mifare, NFC), UHF, or proprietary encrypted systems. Choose the proven, robust, and cost-effective solution.
