The invention brings forward an identification method for an information carrier comprising multi-type identifications. The information carrier can be a product label. By use of auxiliary positioning identification and a corresponding positioning identification detection identification algorithm, auxiliary positioning identifications on the information carrier are automatically identified, such that automatic positioning of multi-type data is realized. By use of an image identification algorithm, such information as characters, bar codes, display contents of display screens, two-dimensional codes, images and the like can be simultaneously identified, and the electronic display screens can display such contents as the characters, the bar codes, the two-dimensional codes, the images and the like, such that the information carrier has abundant information, and the identification results are accurate and reliable. Compared to bar code identification, two-dimensional code identification and image identification, character identification is smaller in characters and high in character segmentation and character identification difficulty. In order to ensure the accuracy of the character identification, the identification results are verified for the character identification by use of already known character lengths.
