The Challenge | Health Makes Wealth
Integrate NASA Earth science data and citizen science data to learn more about the connections between human, animal, and environmental health.
Smart Metro Travel Card
Making the Metro Card available on mobile just like a app where you can just open the app, touch your phone on the Metro Gates and you will be allowed to enter and initiate your trip.
The princle behind the app is very simple.
It works on Near Feild Communication (NFC) . The phone when comes in contact or a range of 4 cm with the Card Reader machines at Metro Station, comminucates with the machine and exchanges some data like Station Code, Journey Start Time. The data being shared is encrypted with a unique key, each time a contact takes place. Then this information is decrypted at the Exit Gate of another Metro station and then distance between the two stations is calculated using the Station Code (pre defined). What happens next is the update in the current balance.
