can I use RFID cr038 for estimating mobile speed using VB? two RFID cr038 and one tag will be used ... tag(placed on mobile objects) speed will be estimated when it was over both the reader ...

CR038 require inquiry/command from the master (example microcontroller or computer) to read the Mifare Card. This will introduce uncertainty delay due to communication and software you developed.

I don recommend it for speed measurement, furthermore, the reading distance is not far enough for it to read the object.

reading distance may be a problem .. but if I only touch those tags in reader , is it possible to do this project? Do you have any suggestions?? thanks
