In most cases, activating this encryption is unnecessary. However, you may choose to turn on the encryption to provide extra security or privacy. Keep in mind that activating fingerprint encryption requires management of encryption keys and should be performed only by advanced users. Activating fingerprint encryption will render all previously saved templates unusable. As a result, it is best to activate the encryption prior to registering users. To activate fingerprint encryption: 1. From the menu bar, click Option > Fingerprint. This will open the Fingerprint dialog box. 147 Copyright ©2014, Suprema Inc. On the web: www.supremainc.com
