And my own custom app.
PS. Syncing like this has been around for well, since I began to code in the 80's. Hardly an emerging technology.
I am doing a project on emerging technologies, I chose to do it on software/hardware that allows a user to transfer, communicate, or access, a specific file from one device to another. I gave the professor to examples of what I meant; the first being NFC as an example of transferring a file from your device to another random devices and the example of icloud making a kind of network where you are able to save a file one of your devices and access it from another set device (in the case of apple, save on your iphone, access on your ipad or mac). Now both of these technologies have been around for a little while and the project is on emerging technology so I am asking for examples of actual emerging tech like these ones but need more developing but can be better because I know they have some problems and I know someone is trying to make them obsolete. I am not asking for you to do the research for me, just ideas. Please help. Even if you just point me in the direction of website that you of that could possibly help.
