Help protect your company's confidential information and control printing access by requiring users to authenticate at your imaging and printing devices with your existing proximity cards. In the past, the wide variety of proximity cards on the market made it expensive and cumbersome to support authentication via cards. HP Common Proximity Card Readers offer support for more than 43 card formats in a single card reader. HP proximity card readers are designed to leverage your existing card system for applications beyond physical security. You can count on easy, error-free identification on both newer and older printing and imaging devices. With the Plug-and-Play functionality of HP card readers, no additional software is required once you have installed HP Access Control Professional in your network environment.
