Affected Products & Versions
All versions (Current version : BioStar 2 Device SDK 184.108.40.206 beta)
When trying the card which is registered in a user with a secure credential card written by SDK sample, access is denied with "event code[VERIFY_FAIL_CARD] CardId[unknown] image"
If you check the card ID, it is written as 0x00.
The wrong sample code for secure card. Sample code writes smart card in the same way for both AoC and secure credential card.
However, in case of Secure credential card, SDK should write different way because Suprema device reads different way for two cases.
In case of AoC(0x03), device reads full 32 bytes but in case of Secure(0x02) device reads only the first 24 bytes as card number.
Change the secure credential card reading part referring to the sample code below.
* You don't need to change library, but only sample code. If you already programmed the part following the manual, you don't need to change.
We will apply the correct code in sample code in the future release.
