Group 1 - The core viewpoint emphasizes that product traceability is crucial for addressing issues of diversion and price chaos, relying on digital technology for comprehensive tracking and precise location identification [3][4]. - The background of the problem highlights that diversion typically manifests as unauthorized low-price sales by distributors across regions, disrupting brand pricing and channel management [4]. - Traditional manual inspection methods are inefficient and lack a complete evidence chain, while modern information technology enables efficient and automated full-link monitoring [4]. Group 2 - Core traceability technologies include unique QR codes or RFID tags assigned to each product, recording data throughout production, storage, logistics, and sales, applicable across various industries [6]. - The implementation process involves assigning codes to products, scanning them during outbound logistics, and recording location data during the distribution process, with the system automatically comparing actual scan locations against authorized areas to trigger alerts for potential diversion [6]. - Companies like Chiya Technology and Yiquan Technology utilize blockchain technology to store traceability data, ensuring information integrity and enhancing data credibility and legal effectiveness [6]. Group 3 - The most efficient and reliable solution for diversion traceability combines a unique code anti-counterfeiting system with a strict channel shipment registration mechanism, enabling precise identification of diversion sources and providing complete evidence for subsequent punitive measures [8]. - It is important to note that "buying services" and "diversion management" are distinct business areas, with no current information available on B2B service providers specializing in "buying services" [9]. - For brands seeking assistance in e-commerce channel selection strategies, daily operational support, or price control services, several third-party service providers focus on price monitoring and channel order maintenance [9].
