In order to help you in the use of the CNA Applet, please download the document How to use CNA Applet.
In order to activate the applets that are installed, do not forget that it requires an activation module (if you are not a Calypso licensee). It is possible to register for purchase of activation modules on the Innovatron web site.
If you need assistance for the integration of the Applet or the use of the activation modules, CNA has mandated some companies to assist you, with the best experts on Calypso. Please send a email to firstname.lastname@example.org
A CNA Specification which is aimed at the NFC Service Providers that want to install a Calypso application on a French NFC phone is available and is an example of the cooperation between MNO and transport operators.
