Functions
UFR_STATUS DL_API	CheckUidChangeableM (UFR_HANDLE hndUFR)
	Function tries to change the UID on the card. Multi reader support. On some cards (e.g. Magic Classic) changing UID is possible. If theed card is that type of card, then the function returns UFR_OK.

ReadTTStatusM()

UFR_STATUS DL_API ReadTTStatusM	(	UFR_HANDLE	hndUFR,
		OUT uint8_t *	tt_message,
		VAR uint8_t *	tt_status )

Function provides the information about the tag tamper status which is detected when the NTAG 213 TT is powered by an RF field.

Multi reader support. From library version 5.0.59 and firmware version 5.0.60

Parameters

hndUFR	handle of the uFR device
tt_message	4 byte Tag Tamper message. “0000” is returned, if the NTAG 213 TT has never detected the Tag Tamper as opened during the startup. If the NTAG 213 TT has once detected the tag tamper wire as opened, it returns the data which have been programmed in page 45 (TT_MESSAGE)
tt_status	status of the tag tamper wire detected during startup. “C” if Tag Tamper was closed at current startup “O” if Tag Tamper was open at current startup “I” if Tag Tamper measurement was incorrect
