Reference Manual for uTrust 3720F and uTrust 3721F Readers
6.3.7.12.
Traverse
Traverse APDU is used to send the “Raw Card Command” in data field to the card without any card
specific processing by the reader and returns the raw response data from the card. The reader only
takes care of protocol specific processing (like CRC, Prologue field,…). This command is intended for
sending ISO15693 custom commands defined by card manufacturer.
The reader uses the Frame Type specified in the P2 parameter field and the Frame Waiting Time (FWT)
specified in the P1 parameter field while transmitting command and receiving response respectively.
