In one aspect, a method includes receiving, at a user device, an instruction for displaying a two-dimensional code. The user device obtains multiple two-dimensional codes corresponding to a user. The user device sequentially displays the multiple two-dimensional codes based on one or more predetermined time intervals, so that the multiple two-dimensional codes form a dynamic two-dimensional code on a display page. A ratio of each of the one or more predetermined time intervals to a validity period of each of the multiple two-dimensional codes is less than a predetermined threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Displaying and recognizing two-dimensional code","description":"This disclosure relates to displaying and recognizing two-dimensional codes.
