Description
The Hikvision S50+TK4100 is a dual-frequency access control card designed for systems that need support for both 13.56 MHz and 125 KHz credentials. This makes it a practical option for mixed environments where older and newer access control technologies may be used together.
Unlike a standard single-frequency card or key fob, the S50+TK4100 combines Mifare 1 + EM capability in one thin card format. It is ideal for offices, commercial sites, apartment buildings, and upgrade projects where compatibility matters.
