buy RFID tags and reader

RFQ Details

Question:
1. 100 meter reading distance can be only made by active tags. Can a RFID flashcard read this distance 100 m?
2. 150 km/h (approx. 42 meters per second) and a distance of 25 meters (one side/both sides) and a reading distance of 100 meter leads to 5 to 10 tags to read at once. The notebook or PDA is in the car. Will UHF or MW waves pass the classis?
3. Can you give me more information about RFID for accuracy positioning?

4. What's the accuracy if I use the RFID for positioning?

5. Is there an interface to a NI Labview application?

I would like to have a price overview of the product. I am only a student and have only a little of the money to buy the product. So please give me a student discount.
