125 kHz Proximity to Smart Credential Migration
One of the most valuable features of the HID Signo 40 Standard Profile reader is its ability to support both traditional 125 kHz proximity cards and newer 13.56 MHz smart credential technologies.
Organizations using compatible HID Prox, AWID, Indala, or EM proximity credentials can plan a phased transition toward HID Seos, iCLASS, MIFARE, or mobile credentials without necessarily replacing every credential at the same time.
As credential migration progresses, supported legacy credential technologies can be disabled through appropriate reader configuration to help strengthen access control security.
