Terminal verification results (TVR) or Tag '95'[1] is an EMV data object . The TVR is a series of bits set by the terminal reading an EMV card, based on logical tests (for example has the card expired). This data object is used in the terminal's decision whether to accept, decline or go on-line for a payment transaction. The format of the TVR is as follows:[2][3]

Byte 1
b8 b7 b6 b5 b4 b3 b2 b1 Meaning
1 Offline data authentication was not performed
1 SDA failed
1 ICC data missing
1 Card number appears on hotlist
1 DDA failed
1 CDA failed
1 RFU (Now SDA was selected)
0 RFU
Byte 2
b8 b7 b6 b5 b4 b3 b2 b1 Meaning
1 Card and terminal have different application versions
1 Expired application
1 Application not yet effective
1 Requested service not allowed for card product
1 New card
0 RFU
0 RFU
0 RFU
Byte 3
