LTAC (Luxury Traceability Chain) tracks the movement of tangible goods or intangible information. By registering each transaction, it enables traceability from initial data collection, raw material sourcing, manufacturing process, processing stages, warehousing information, batch inspections, logistics turnover, to third-party quality inspections, customs entry and exit, and anti-counterfeiting authentication. This ensures the accuracy and security of supply chain data services based on luxury traceability information, thereby providing supply chain financial services to participants in the industry.
