There's a minor discussion in another thread, and a key point (to which nobody seems to have the answer) is whether an app on a phone can do the following :
Person A has phone A, which contains an app which A has loaded.
Person A tells person B a web address, and asks him to link to that address using his own phone (call it ... oh .. phone B).
B goes to the webpage, and it asks B to enter some information. B does so.
The claim is that the app on phone A can pick up the information which B has entered into the website.
The information entered would be 2N and 1A, possibly in an order set by the website.
Would this be feasible?
It's just occurred to me that phone A could merely listen to the beeps as the keys are pressed on phone B. In addition, the alpha character will be one of a set of four, each requiring a different number of presses of the numeric keys.
