Hello everyone ... glad to have my first post on this helpful forum.
I have a senior design project, it is A battery operated RFID with built-in GPS for car tracking and ticketing. it's a card-like module to be installed on a car.
As I know there should be a GPS module that determines the location, and an RFID module that stores the ID information. both RFID and GPS modules should send their data continuously to the receiver at least 100 Meter faraway. the battery also should last at least a complete year.
I want design my project on Arduino board, but I have some questions:
1- what RFID, GPS modules and battery do you prefer me to use for the requirements above ?
2- can these three modules be integrated with an Arduino board together ? How ?
I know that "How" part is a long story, but I need to have some clarifications, hints or some previous work, references to refer to. and thanks deeply much for those who can help.

Why are you using RFID?
Are you going to be reading RFID cards or tags?
It sounds like you just want your GPS device to have a unique ID. I don't see where RFID comes into play.
Use Google location tracking on an Android cell phone. The battery will need to be the size of a small suitcase and therefore will cost about $5000 which means the running cost will be about $13 per day.
thanks so much for all of you guys ... I really appreciate your help ..
Now I understood the limits of my project ... but it seems that the 100 meter is a must due to specification requirements, however, it is not important for the data to be send in continues manner, at least it must send it once required by the reader, say a police officer on the road. can I have such a battery for this operation ?
the idea of Mr. DuaneDegn is interesting for me, can I store 10-digits ID number on the GPS and send it combined with location through just an Arduino and GPS chip ?
Yes that is no problem.
You will then be making what is known as a transponder, it gets a message and responds to it with your data.
As you are in a car why not use the car battery for power?

thank you so much my friend .. really happy of your response .
thanks also for confirming the idea for me, so I will use the GPS chip for storing the ID also with Arduino only and then make an experiment. due to the car battery you suggested, the problem is that Iam restricted with small battery according to my adviser requirements, all the parts of the project should be cased in box with predetermined size, the gps, the controller and the battery. they are trying to make it a bit challenge .. you know.
thanks again for all of you , I will be back soon if I face any problem.

Look at something like the 63mw Xbee which should be able to do 100m+ line of sight. It draws 50mA at 3.3v in listen mode. That's a big problem.
To increase battery life you need the average current to be much less which means putting it into sleep mode for some large fraction of the time.
Are you only interested in the GPS location when the vehicle is visual range of the police officer? If so, why?
GPS is only going to give you 5m accuracy which isn't good enough to pinpoint a single car in a crowded car park. Ideally you need the headlights to flash etc.
I have put together a project with the FONA 808 that sends data via 2G to a server location. It's is a simple setup using the 808. The biggest issue is the power source and management.
There are solar rechargeable modules or devices that can generate power from kinetic energy of the wheel. All require a 'sleep mode' for when the car is turned off.

Look up the FONA 808
thanks deeply much guys ..
to be honest, I wouldn't to understand such limits without your help ... Iam somehow a newbie and don't know where to start, however, you gave me a wide line of sight into the project.
yes, Iam interested only in the GPS and the noticed accuracy is sufficient considering my project limits and requirements. I need to have simple module that does an elementary job and convince my advisers that I have done something. other ways, communication is not my major but certain conditions in the faculty have lead me to this kind of project.
initially and based on your suggestions ... I decided to have only GPS module with a controller and battery, the gps is to have a unique ID number and send the location data. about the battery requirement, my advisers haven't put any limits on how the data should be transferred. their only point is that data should be transferred wireless to at least 100 meter. As a want, they said that signal may have some kind of encryption, basic encryption. they said nothing about the technology of the transmission leaving it open for me.
I will search about the FONA 808 and back, thanks a lot my friends.
