Figure 2 represents a more conceptual view of ATOP from a system point of view, showing three
main components:
 Application processor: This processor will run code specific to the application (road
tolling, insurance ...) which is portable from one platform to another one in order to avoid
recertification. The application drives the three following conceptual co-processors:
o A Positioning processor provides accurate location information to the
application;
o An NFC processor
2
provides connection to an external bignette, card reader, or
other NFC enabled device to increase application security;
o A Communication processor allows the application to connect to servers and
receive update and notifications, receive or generate voice call or SMS.
