MIFARE (NXP Semiconductors) Compatible Cards & Fobs
MIFARE is NXP Semiconductors' family of 13.56 MHz contactless smart card platforms, ranging from the widely deployed but cryptographically broken MIFARE Classic (1K and 4K) through the AES-secured MIFARE Plus and the high-security MIFARE DESFire EV1/EV2/EV3 series. American Key Cards supplies compatible cards and fobs across the full MIFARE portfolio: Classic 1K/4K and Ultralight for legacy and low-security systems, Plus for Classic-to-AES migration, and blank DESFire EV1/EV2/EV3 for new high-security deployments — with honest disclosure that secured DESFire credentials cannot be cloned or duplicated.

MIFARE Classic 1K
MIFARE Classic 1K is the world's most-deployed contactless smart card format, running at 13.56 MHz with 1 KB of CRYPTO1-protected memory across 16 sectors — widely used in legacy access control and hotel lock systems but known to be cloneable.

MIFARE Classic 4K expands on the 1K format with 4,096 bytes across 40 sectors for multi-application campus and transit use, but shares the same broken CRYPTO1 cipher that makes all MIFARE Classic cards cloneable with off-the-shelf tools.

MIFARE DESFire EV1 is NXP's first-generation multi-application secure smart card, offering AES-128 and 3DES hardware encryption at 13.56 MHz with EAL4+ certification — not cloneable, suitable for legacy high-security deployments, but superseded by EV3 for new installations.
View compatible cardsMIFARE DESFire EV2
MIFARE DESFire EV2 is NXP's second-generation multi-application secure card with EAL5+ certification, AES-128 encryption, anti-relay proximity check, and Transaction MAC — not cloneable, widely deployed in enterprise and government access control.
View compatible cardsMIFARE DESFire EV3
MIFARE DESFire EV3 is NXP's current-generation flagship smart card — EAL5+ certified, AES-128 only (single DES removed), with Secure Unique NFC messaging, 1 million write cycles, and extended read range — not cloneable, recommended for all new high-security deployments.
View compatible cardsMIFARE Plus
MIFARE Plus is NXP's drop-in AES-128 upgrade path for MIFARE Classic infrastructure, offering backward-compatible SL1 mode (readable by Classic readers) and fully secure SL3 mode (AES-128, not cloneable) on a single card platform.
View compatible cardsMIFARE Ultralight / Ultralight C
MIFARE Ultralight and Ultralight C are NXP's ultra-low-cost 13.56 MHz NFC tags — no crypto on the base variant (trivially cloneable), 3DES on Ultralight C — suited for disposable ticketing, transit passes, and loyalty cards, not for secure access control.
