Abstract
A user accesses a control server using a web-browsing function provided in a cell phone to select purchase data, and sends an identification number specifying an in-vehicle device to be downloaded with the data. The control server sends a one-time password to the cell phone. The user inputs the one-time password into the in-vehicle device. When the in-vehicle device gets into one of download cells, such as a rail station, the ID and the one-time password are sent to the control server through an access point. The control server conducts conformation that the received ID and the one-time password are identical to those sent and received previously. When being confirmed as being identical, the requested data is delivered to the in-vehicle device through the access point.
