Systems, devices, and methods for displaying a barcode at a computing device

摘要

Embodiments of the systems, devices, and methods described herein generally facilitate the display of a barcode at a computing device for capture by another computing device. In accordance with one example embodiment, a barcode is generated at a first computing device, the barcode is displayed on a display screen associated with the first computing device, and one or more display properties of the barcode are dynamically modified while it is displayed at the first computing device until the barcode is successfully captured (e.g. by a camera) at a second computing device.

主权项

1. A method of displaying a barcode at a computing device, the method performed by a processor of the computing device, the method comprising:
generating a first version of a barcode encoding data for display on a display screen associated with the computing device; displaying the first version of the barcode on the display screen; generating a modified version of the barcode encoding the data of the first version by modifying one or more display properties associated with the barcode; displaying the modified version of the barcode on the display screen; responsive to receiving a signal to terminate display of the barcode:
terminating display of the barcode; and responsive to not receiving a signal to terminate display of the barcode:
generating an altered version of the barcode by altering the same one or more display properties associated with the modified version of the barcode; anddisplaying the altered version of the barcode, wherein the barcode is generated from a base pattern and a layer having at least one modifiable property, and wherein generating the modified version of the barcode comprises modifying one or more of the at least one modifiable property of the layer, and applying the layer to the base pattern, wherein the one or more of the at least one modifiable property of the layer is modified based on a value of a time-dependent continuous mathematical function.
