METHOD FOR GENERATING ANNULAR TWO-DIMENSIONAL CODE AND STAMP USING TWO-DIMENSIONAL CODE

摘要

Provided are a method for generating an annular two-dimensional code, and a stamp and a device using the two-dimensional code. The method comprises: generating a first hollow model with an annular structure; and arranging, in a circumferential rotation direction, two-dimensional code data streams in the first hollow model to generate a code pattern image.
