So let's imagine you are traveling around the world and you visit a certain country and meet some interesting and beautiful women from some other part of the world, let's say from Germany, just for the argument sake. You talk to them and then it hits you, they are heading towards the airport on their way to Poland, and that's exactly where you are headed as well. You wish to exchange contacts with them, how will you do that?
You don't have a pen and paper on you, so what do you do?
Well the answer is very simple – create an app. So the app works like this. You sign up and simply input all your contact details you wish to share. If you want to share the details who has the same app as you do, just add the person's unique ID.
One other important and handy thing is that you can add this person offline and once you restore your Internet connection, your smartphone will automatically retrieve the information and sync it with your smartphone. Easy as 1, 2, 3….
But what if that person does not have that app? I mean, has he/she been living under a rock somewhere?
This is where things get interesting, you can simply select an option to send your travel card – meaning the app to her/him using nothing more the an email or WhatsApp, when you regain your Internet connection again.
