Well yes, but also no.

The data is all contained in the QR codes, but it's also contained in the cache of the sender (which is how any chunk can be arbitrarily retransmitted), and also in the cache of the receiver (which is how the data is validated).

    Well it's kind of obvious the sender has the plain data right 😌 and temporarily stored in the receiver somewhere.

    Does it play like a qrcode video, or is it more manual?

    I suppose that's true lol.

    Yes, it plays a video with an adjustable speed, or you can have it show a specific frame. The receiver has a grid that fills in as the data is received, making it easy to tell what data was or wasn't successfully received.
