Hi Dhiraj! You'll want to make your project simple just to demonstrate this concept. Don't need to make it complicated. Things you need to focus on:
1) What kind of data you need to collect. E.g user account ID, an authentication string/password, toll booth ID, etc
2) How to read from the car tag/device. Maybe using IR or RFID?
3) How to transfer this information to a database. tag reading can be connected to laptop via USB or serial. Or, you can use an Ethernet board with a microcontroller that will connect to laptop.
4) What kind of database used. SQL? You might need to know how to manipulate SQL queries using C, VB or whatever you're comfortable with. The SQL tables will contain your information, including how much credit
5) Display amount deducted and amount left in the toll account. Simple GUI to display this information.
If your project scope is more specific, then just focus on those. Try to research more ideas based on the above focus points 😀
