The RF IDeas pcProx Plus 82 Series card readers are dual-frequency readers that can read both 125 kHz proximity cards and 13.56 MHz contactless cards from a single badge. This allows customers to leverage their existing employee ID badges for multiple applications beyond physical access control. The readers integrate with software through a DLL and can deliver card ID data to applications in a format they understand, enabling uses like user authentication, time and attendance tracking, and more. They are compatible with Windows, Linux and other systems and support many common ID card technologies.
