As you can see in the figure below, three different signatures have been defined. You can also choose which security groups are allowed to sign a particular signature. For instance, in the figure above, only members of the Pathologist group are allowed to approve the layout.

It is possible to sign a document at any time. Simply select File tab-> Info-> Digital Signatures-> Sign from the main menu. A list of available signatures will appear and the user can select the desired signature. After pressing the Sign button, the user is prompted to enter their password to confirm their identity, as shown below.

If the logging features are enabled, a complete log of all signatures is kept. It then becomes possible to see every time the document was signed and unsigned.

Tokens are a powerful feature in FCS Express that allows the text on your report to automatically update based on the current state of your analysis. A complete set of Signature Tokens allows you to embed signature information within any text box. Since the text boxes are complete word processors, that means that you can format your signatures in whatever manner you like and place them on the layout in any position you desire.

Signatures can be set to allow or not allow manual signing and unsigning. Signatures can also be allowed or not allowed based on a token. This feature can be used to enforce a Signature Order where a signature from one particular signature group must be signed before a signature from another signature group is allowed. By utilizing the Allow authorized user to sign/unsign based on a token feature, and using the Signature Status of particular signature groups to evaluate the token to true or false, signature orders may be enforced. The Allow Signing/Allow Unsigning options are defined in the table below.
