This sounds like a fairly straightforward RFID application. I would probably recommend that the data not be stored on a chip, but rather in a database. As the cars are loaded into the starting gate, each car’s tag could be read, and the system would then look up all information associated with that vehicle in the database, displaying it on a monitor for the announcer.
I suggest you contact the Dayton RFID Convergence Center. The experts there can probably put you in touch with a vendor that can supply a solution. You might also want to reach out to RFID Enabled Solutions, located in Dublin, Ohio.
