The invention provides an application platform for a combined-type label in a commodity field, and the platform comprises a two-dimensional code, a sub-platform based on the two-dimensional code, an invisible code, and a sub-platform based on the invisible code. The two-dimensional code is used for achieving code-scanning input, obtaining service tracing information, achieving code-scanning selling in a shop, carrying out code-scanning drawing, and achieving code-scanning sales promotion. The sub-platform based on the two-dimensional code comprises a server based on the two-dimensional code, a tracing system, a sales system, a drawing system, a sales promotion system, and a data analysis system, wherein the tracing system, the sales system, the drawing system, the sales promotion system and the data analysis system respectively carry out interaction with the server. The invisible code is used for achieving the authenticity verification of garments, and is also used by an inspector in a garment factory for inspecting the information of sales places of current garments. The sub-platform based on the invisible code comprises a server based on the invisible code, an authenticity verification information system, and a garment sales place inspection system, wherein the authenticity verification information system and the garment sales place inspection system respectively carry out interaction with the server based on the invisible code. The platform can enable the garment factory to know each link of the whole process of each garment from production to sales.
