I saw a video on YouTube where a bitcoin enthusiast showed how to send bitcoin through a tv screen using a smartphone's scanner. The smartphone was held up to the screen and scanned a QR bar code to make the transaction, which was just a transmission of data onto the phone. Of course, the Bitcoin model relies partially on an existing internet connection to confirm the transaction but if the transmission is one way an internet connection would not be required.
I realize not every part of the world has televisions but couldn't existing global channels transmit such data right now right through the screen to tablets and smartphones by scrolling different QR barcodes across the screen?
Not sure if this is applicable to Outernet (television channels can be highly regulated in authoritarian nations) but we were discussing mesh networks in another thread and the problems associated with them and long distance data transmission and it just dawned upon me the existing infrastructure for video transmission of data is already there, at least one way transmission..
All a startup would have to do is set up a tv channel with global distribution or rent time on one and broadcast data barcodes that could be scanned for their data by smartphones held up to the screen.
