Intertool is a SaaS solution developped by GCN ITS for the analysis of Calypso portable objects. Intertool implements Intercode (NF P99 405) and AMC (NF P99 508) application data models

The Intertool software has been specially designed for consulting companies, transport authorities, operators requiring a Calypso portable objects and applications data analysis tool, independant from a specific ticketing system integrator.

Intertool's major advantage resides in its SaaS architecture, allowing remote and shared access to portable objects data.

Intertool can also be connected with a test case tool, sush as TestLink, to provide an integrated online test environment, ideal for ticketing systems interoperabilty acceptance tests

Intertool also benefits from constant updates.

The installation on the end user computer has been reduced to the strict minimum: a PC/SC compliant NFC reader, and a small footprint client software.
