Our company is going to be implementing a system whereby students are issued a ridership card, and a card reader is installed on school buses. This is to help parents and school officials locate students should one get on the incorrect bus or go missing. It is important to note that readers are installed only on the buses and nowhere else, meaning that the only information that is sent to a secure database is the student's boarding and un-boarding status.

I'm wondering if anyone has any ideas as to what this pass program can be called? We want something fun, but it is important to emphasize that this "pass" or "card" does enhance safety and provides a peace of mind for parents. Thank you!
