The GuardDog is a miniature, fingerprint authentication unit that compares stored fingerprint 
templates with fingerprint data acquired in real time. The GuardDog is part of Biocentric 
Solutions CombiFamily of products, which includes the CombiReader™, CombiMemory™, 
and CombiSmart™.

All Combis, including the GuardDog, are intelligent devices that can verify the identity of an 
individual by scanning his or her actual fingerprint and comparing the scanned print with 
fingerprint data (called a template) printed or stored on a personal token. The verification is 
performed at the device, so no fingerprint data need be stored in or transmitted to a central 
database.

The GuardDog offers a simple, easy to use, and reliable solution for a variety of security and 
access control challenges in harsh environments. It is especially designed to withstand 
moisture, heat, and cold and can be operated as a stand-alone unit or included in a network.

Typical GuardDog applications include:

• Stand-alone identity verification where the GuardDog confirms that a person is the rightful 

holder of a token (an iButton or contactless smart card) that he or she is carrying.

• Access control where the GuardDog confirms the identity of the carrier of a token and inter-

faces with other access control devices, such as alarms and door latches. The comparison of 
the scanned print with the fingerprint data is done in the GuardDog so no fingerprint infor-
mation is transmitted to another computer. In an access control application, the GuardDog 
can work autonomously (storing all access control information locally) or in a network con-
figuration with critical information (other than fingerprint information) stored on a security 
server. 

• Time and attendance where the GuardDog confirms the identity of a token carrier and also 

generates a log entry for each transaction. Just as it can in an access control application, the 
GuardDog can work autonomously or in a network configuration in a time and attendance 
application.
