This is a passenger tracking app, a bus start from a  place and it will take 4-5 hrs to go to reach destination. during this journey bus will halt 3-4 times . each time passengers can out from the bus and in again after few mins. But sometimes some passengers miss the bus and its hard to track who is missing. For this purpose need a tracking system, so that each time passenger will scan that QR code before out the bus and when enter again. So system will know which passenger is in/out before start the bus again.

Only need a validation , scan by camera that QR code of passenger.

1) User (bus operator) will upload a CSV file with fields, passenger id, passenger name, bus number, date time slot, QR code for each passenger
2) Bus operator will scan QR code for each time for a passenger if he want to out and scan again when he enter the bus again. system will count this each time and make ensure if the passenger is present on bus or not before start the bus again.  

This all need to work without internet in OFFLINE mode.

So operator will upload csv file from his mobile and all scan checking from that csv file data.

Its a simple validation app scan by camera.


Let me explain the step again

1. Upload a CSV file in offline
2. Scan QR code for each passenger each time when they go to outside from the bus and update in local db that a person go to outside
3. Scan the QR code again for this passenger when he return to the bus again and update in local DB
4. During the bus journey passengers can in/out several time for little break , lets say 5-6 times and every time they need to scan their QR to validate that they OUT / IN to the bus
5. After complete the journey bus operator will update the local db to server by clicking a single SYNC button
