AgnosTVR (DF72) is a specific 30 byte long bitmap used to trace framework's behavour. It provides a way to get internal information from the kernels:
TVR: some kernels require to reset TVR to 0x00 at the end of the EMV processing. AgnosTVR mirrors this tag so that it's always possible to get that standard EMV bitmap
ODA: ODA is a complex multi-step cryptographic EMV processing that may lead to many different issues. AgnosTVR traces all possible outcomes
Contactless kernels: each kernel implements a specific processing and supports a different level signals. AgnosTVR provides a specific bitmap when specifications suffer from a lake of errors management
Contact kernel: the TVR is the main dashboard used to analyse EMV events occurrences during a transaction. AgnosTVR provides additional traces
To get the exact AgnosTVR bitmap, go to ACE and click on the left side of the tag’s value from Transaction page.
