This RFID cabinet lock is designed for secure, discreet installation inside wooden cabinets, drawers, or storage boxes to restrict access to sensitive items like medications, sharp tools, or alcohol. It operates using RFID technology with programmable key cards or NFC-enabled smartphones, supporting up to 13 unique credentials per lock. The lock body remains fully concealed within the cabinet structure, eliminating external hardware that could be tampered with or forced. It accommodates varying door thicknesses depending on card type-white cards work through wood up to 4.5 cm thick, while blue cards support up to 2.54 cm. Power options include 4 AAA alkaline batteries (not included), offering approximately 6 months of operation or 6,000 unlocks, with optional Type-C or wired power input. Installation requires no visible drilling on exterior surfaces and integrates cleanly with standard cabinetry. Compatibility includes both Android and iOS devices via NFC, and setup guidance is available through instructional video resources. The system allows flexible credential management across multiple locks and keys, enabling shared access control without physical key duplication.
