Schlage AD-series - MT Reader Head Compatibility with HID iClass SEOS Credentials

The MT and MTK reader heads for the AD-series locks will ONLY read the public CSN of iClass cards, which with SEOS means a different random CSN every time the card is read.

Recommendation: Use Si or SiK reader heads instead.  These have an iClass decoder chip built in to read the secure sector of standard iClass SEOS credentials.
