Abstract
Systems/techniques that can facilitate video/animated QR codes are provided. In various aspects, a processor can identify a QR code. In various instances, the processor can decompose the QR code into a static fragment and a plurality of dynamic fragments. The static fragment can be a portion of the QR code that contains sufficient information to facilitate an online transaction, whereas the plurality of dynamic fragments can be a plurality of portions of the QR code that collectively contain sufficient information to facilitate an offline transaction. In various instances, the processor can sequentially render a plurality of frames on an electronic display, where each frame depicts the static fragment and a corresponding one of the plurality of dynamic fragments. Accordingly, a point-of-sale device can facilitate an online transaction by scanning one frame rendered by the processor, and/or can facilitate an offline transaction by scanning all frames rendered by the processor.
