The Gemalto IDPrime MD 830 is a Plug & Play Javacard. "MD" stands for Minidriver, which means that a MiniDriver is loaded for this card via Windows Update and can then be used via the Microsoft Base Smart Card Cryptographic Service Provider (MS Base SC CSP). The Gemalto IDPrime MD 830 should therefore be used the same way as the Gemalto .NET.
The IDPrime MD 830 is a contact-based smartcard, FIPS 140-2 Level 3 & FIPS 140-2 Level 2 certified for the Java platform and the combination of Java platform plus PKI applet.
