There are possibly new student cards that are unsupported (DESFire v3) #10
Description
Today at the drink we encountered one recently replaced student card that did not work on Juliana 3.1.
Unsure if it works on 3.2, but that should technically support it, however 3.2 is not used a lot due to driver issues.
More investigation is needed
The new cards work fine on Juliana 3.2. Please upgrade to the latest version if you experience problems.
