When opening a bank statement in the Sign Live! CC Sparkasse Edition it will be validated automatically. This can take a few seconds. Once this process is complete, you will see on the left side of the screen on the "Sidebar" that the signature is valid.
If the message "Identity is unknown" appears in the validation report, you probably have an old version of the Sign Live! CC Sparkasse Edition in action. Please take one update to the current one Sign Live! CC SPARKASSEN edition before. You can obtain access to the current version from your Sparkasse.
