Well to be frank some of the ideas are based on different concepts already available.I have heard a few years back of a
samsung phone capable of reading the Visiting card.
Well as always, not very sure if such an app exists. Well if it
doesn't then I expect to code it some day in the nearest future.
This idea came after seeing a Android Application for Bar code reading
goCart.
We can develop an application for use in Camera phones which can have a snapshot of visiting card and then parse the photo. After parsing the details in the visiting cards are organized and the person detail and location are
updated on a Map.
Next time when you are travelling on a particular road and your appl is on you
Can know who is around that area whom you know.
For e.g I scan a Visting card of a person in J P Nagar 6th Phase , and 1st main, the next time I go by this route I can see the details of the person who is nearby in my mobile app.Also all his details.
This can always help in case of emergencies.
