Technical principles: Absorptive Layer Design: An absorptive material is placed between the tag and the metal surface to counteract the impact of metal on RF signals, allowing the chip to transmit and receive signals normally Antenna Optimization: Special antenna shapes (such as meandering antennas) are used to alter the signal propagation path and avoid interference from metal. Application scenarios: Industrial Equipment Management: attached to metal tools (wrenches, instruments) and metal equipment (machine tools, servers) to achieve tool borrowing and returning management, as well as equipment inspection records Automotive Manufacturing: affixed to metal automotive parts (engines, chassis) for tracking part information during production processes to ensure quality traceability Logistics Metal Containers: applied to metal shipping containers and metal pallets to automatically identify container identities and store cargo information during logistics operations.
