Card Acceptance Wizardry Support
- Frédérick Caron (Unlicensed)
Sometimes, even with the best efforts, card acceptance is an obscure science that only field experience and digging into the different card brand specifications can provide the correct knowledge to understand the behavior in front of you.
This knowledge base is there to help support when a Card is not being accepted as expected.

When looking at tag 0x95 (TVR) we can see that the B1b3 is raised (CDA Failed). This is never good. It means that either the public key is not configured for this RID or that the value is incorrect.
B1b4 and B1b7 could also raise the same behavior.
On Arkos/Atheos, the configuration should be checked to ensure that an E3 Entry is present for this RID / Key Index combination.
If you are using a personal card on a dev terminal, you probably don’t have the production keys.
