Embedded electronic authentication ensures that sub-systems, accessories and attachments, used with or within a piece of equipment are not counterfeit. By employing electronic authentication a manufacturer can more fully control the usage and performance of their products. Depending on the application, electronic authentication helps to maintain product reliability, accuracy, safety, and security and can also protect profit margins.

In the past systems manufacturers have employed physical authentication: expensive molded plugs or connectors, or unique form factors that would only accept the manufacturer's genuine components. These physical techniques are expensive and inconvenient for the manufacturer, and forgers are able to defeat this form of authentication. System designers are moving to electronic authentication because it allows the use of standard interfaces so products have a lower manufacturing cost, and because electronic authentication systems can be economically impractical to defeat.
