The Delta3 is a mullion mounted 13.56 Mhz Smartcard reader for direct mounting to door frames.  A black snap on cover included.  A rear spacer is included also to ensure performance of the reader when mounted on a metal surface.  The Delta 3-(CSN) version returns the CSN (serial number) of the MiFare card as a card ID and the standard Delta3 can be ordered to read sector information.
