Summary: in order to access DoD sites passwords are no longer needed. with CAC access allow you to secure entry with out the painful need to retype a user name and password and if you are able to access remotely from home a CAC reader is needed. i will be honest that there is no real difference from this device to any other just that it sands up which is really nice.
Summary: This reader is heavy, durable, and easy to install. I like it because it's weighty enough that you can pull your card in and out without having to hold onto the reader, and doesn't get in the way like a card reader built into your keyboard is likely to do. If you're trying to decide between this and other similarly priced Smartcard readers, this is the one you want.
