Support mixed credential environments with a reader designed to handle both legacy 125 kHz badges and 13.56 MHz NFC credentials at the same access point. The 2N AU 2.0 RFID reader helps simplify upgrades in buildings where older cards still need to work alongside newer mobile and smart-card workflows. For infrastructure teams, that means fewer exceptions at the door and a cleaner path to credential standardization. It is a practical fit for offices, campuses, and controlled-entry areas where access reliability matters more than feature noise. By accepting multiple credential types, it reduces friction during phased rollouts and helps preserve existing badge investments while you modernize the access stack. Backed by Axis Communications, this reader is positioned for professional access control deployments that demand consistent authentication at the edge. It is a strong choice when you need one reader to serve both transition projects and steady-state operations, without overcomplicating the door hardware design.
