Once the activation of your IsaKey has been completed, you need to subscribe to the Isabel 6 modules before you can start working with Isabel 6. You manage these modules yourself as a user.
Starting from the Welcome page, you can always recall the subscribe to modules window to activate or deactivate modules (e.g. Switch from a Signer module to a Standard module in Isabel 6).
There are 2 major modules. Choose one of them:
Standard module: Consult your accounts, enter and upload payment orders, sign and send them,…
Signing module: Sign transactions
The standard module has submodules that provide more functionality.
