Differences between MIFARE versions
Classic 1K/4K: widespread, economical, compatible with legacy systems; its cryptography is weak by modern standards. Plus: backwards compatible with Classic while enabling AES migration. DESFire EV3: AES-128 encryption, multi-application support and the highest security level.
For a new hotel or corporate campus we recommend DESFire EV3; for an existing Classic estate, Plus makes a clean migration path.

Frequently asked questions
+Can MIFARE Classic cards be cloned?
Classic 1K uses Crypto1, which has known weaknesses. Where security matters, choose DESFire EV3 or MIFARE Plus.
