Single page file transfer using QR Codes and a browser. Sending device loads a file into the page, gets chunked. Receiver gets all the chunks through a camera, tosses lightly and reassembles, CRC to garnish. Designed to push data from an old phone that had broken comms after it took a swimming lesson in a coffee mug, it's been quite handy.
If the phone had broken comms, how did you get the code onto the phone to run?
In ye olden days we used cables to sync all of our apps and data to our phones.
But why not move the data over that cable? Some kind of iOS thing that made that more complicated than pushing an app to the phone?
Interesting idea! A demo video would be great :)
