All HID™ Indala 125 kHz Proximity Cards feature FlexSecur® technology, which provides an added level of access control system security through a verification process at the reader. Unique to the HID™ Indala product line, FlexSecur® screens out unauthorized cards prior to sending card data to the host system. The Indala Credentials are available in a wide variety of styles suitable for every application. Indala Credentials are compatible with all Indala readers and can be easily encoded with the Indala ProxSmith® Programmer and toolkit. Plus the passive, no-battery design of HID™ Indala proximity cards allows for an infinite number of reads and is warranted against defects in material and workmanship.
