The trial service, available until July 2004, offers a diverse menu of functions including office access control, employee attendance tracking and network authentication as well as cashless purchasing.

The system includes postpayment capabilities, linking the employee's spending at the office to his or her own credit card account. Employees can monitor outstanding balances and view a detailed history of transactions on their mobile phone displays with "JCB Office Purchase Inquiry", a downloadable java-based application.

JCB says it is examining the possibility of adding a mobile online function for users to request increases in credit limits.
