This Escape command is supported through the 

READER_GENERIC_ESCAPE

 message.  

This command can be used to disable the contact slot until it is re-enabled through the same 
command or until the reader is re-plugged. When a dual interface card is placed in the contact 
slot it will get detected in both “contact” and “contactless” mode. To enable applications to 
actively switch the detection from contact-only mode to contactless-only mode this Escape 
command can be used along with 

CNTLESS_ SWITCH_RF_ON_OFF

.
