hello,
I 'm in a puzzle about the SFGT.
In 14443, what role the SFGT acts ?

Here is the description of SFTG in EMVCo ®* Type Approval Contactless Terminal Level 1 specification,
The delay between the end of the sequence containing the ATS and the beginning of the sequence
containing the first I-Block of an EMV Contactless transaction is at least equal to (SFGT+SFGT)
as requested by the LT in the ATS .


In a simple word, Minimum Frame Delay Time after ATS.
