So anyone with their bluetooth device turned on would automatically receive the image? Your bluetooth would search for other activated bluetooths and send the pic to whichever device is turned on?
No, the recipient would have to accept it, but MY thinking is that they would most likely accept it as it could only have been sent from within the Kingdom Hall because of the range. So, they wouldn't be suspicious of who it came from, a fellow JW (but they'd know a flier would have come from an outsider). So far better chance of successfully delivering info.
