TraceCase is the small and handy contactless spy tool for NFC sniffing discreetly into transactions under real-life conditions. The powerful TraceCase software allows analyzing and debugging in order to create a reliable NFC ecosystem.

Together with TraceCase Toolbox the user receives a command-line based control interface to operate TraceCase remotely. This facilitates the integration into an existing test environment.
