Abstract
This disclosure relates to displaying and recognizing two-dimensional codes. 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.

-20. (canceled)
A computer-implemented method, comprising:
- receiving, at a user device, an instruction for displaying a two-dimensional code;
- obtaining, by the user device, a plurality of two-dimensional codes, wherein the plurality of two-dimensional codes are arranged in multiple groups;
- and
- generating a dynamic two-dimensional code by sequentially displaying, by the user device, the plurality of two-dimensional codes based on a plurality of predetermined time intervals, wherein sequentially displaying the plurality of two-dimensional codes comprises displaying a first quantity of two-dimensional codes in each group based on a first time interval, and sequentially displaying the multiple groups of two-dimensional codes based on a second time interval different from the first time interval.
A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
- receiving, at a user device, an instruction for displaying a two-dimensional code;
- obtaining, by the user device, a plurality of two-dimensional codes, wherein the plurality of two-dimensional codes are arranged in multiple groups;
- and
- generating a dynamic two-dimensional code by sequentially displaying, by the user device, the plurality of two-dimensional codes based on a plurality of predetermined time intervals, wherein sequentially displaying the plurality of two-dimensional codes comprises displaying a first quantity of two-dimensional codes in each group based on a first time interval, and sequentially displaying the multiple groups of two-dimensional codes based on a second time interval different from the first time interval.
A computer-implemented system, comprising:
- one or more computers;
- and
- one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
- receiving, at a user device, an instruction for displaying a two-dimensional code;
- obtaining, by the user device, a plurality of two-dimensional codes, wherein the plurality of two-dimensional codes are arranged in multiple groups;
- and
- generating a dynamic two-dimensional code by sequentially displaying, by the user device, the plurality of two-dimensional codes based on a plurality of predetermined time intervals, wherein sequentially displaying the plurality of two-dimensional codes comprises displaying a first quantity of two-dimensional codes in each group based on a first time interval, and sequentially displaying the multiple groups of two-dimensional codes based on a second time interval different from the first time interval.
