Abstract: A detailed identification method for articles has an image-taking step and a comparison step. The image-taking step includes acts of using a portable identification device having a close-up lens and a screen to take a detailed image of an undistinguishable article and displaying the detailed image on the screen with an enlarged size. The comparison step includes acts of recalling a detailed image of a legal article from a database and displaying the detailed image on the screen of the portable identification device with an enlarged size. The two detailed images are displayed on the same screen so a user can clearly compare the detailed images to judge whether the undistinguishable article is a fake. The detailed identification method for articles has mobility and can be conveniently and extensively used.
