The Campus Card Service System is a web-based mobile software
that allows students and employers to transfer money from their
bank accounts to their campus cards and pay consumption fees on
campus using their campus cards. You should investigate the

campus card. The money is sent to the campus card issuer's public
bank account and used to store the value of one's campus card. The
value of a campus card is not refundable in our system.
