Does anyone know how to get the number of PIN attempts a smartcard or token. NET or C / C + +?

Solución

The only standardized way (ISO 7816-4) is, to send a VERIFY command. If the card responds 63Cx, then x is the number of retries. If it doesn't, a proprietary command may exist to find out. But there is no generic command and there is no other way than to look into the manual of the smartcard or token.
