Honeywell ODPEV28N38 Mifare DESFire EV2 8K Credential Card

Overview

The ODPEV28N38 is a Mifare DESFire EV2 contactless credential card with 8KB of onboard memory, built for commercial access control deployments that require encrypted, high-capacity credentials rather than legacy low-frequency prox cards. DESFire EV2 uses mutual authentication and AES encryption at the card level, which matters if you're replacing prox credentials that can be cloned with inexpensive handheld readers. The 8KB memory pool gives you room to provision multiple applications on a single card — building access plus a secondary use case like cashless vending or time-and-attendance — without reissuing cards later.

Compatibility

As a Mifare DESFire EV2-format credential, the ODPEV28N38 is built to work with reader hardware and access control panels that support the DESFire EV2 standard. Confirm your specific reader model is configured for DESFire EV2 read mode before deployment — DESFire EV2 cards are not interchangeable with standard Mifare Classic or low-frequency 125kHz prox reader infrastructure.

Installation Notes

No card-specific programming, encoding, or badge printer settings are included in manufacturer documentation for this listing — coordinate encoding and site-key provisioning with your access control system administrator prior to rollout to keep card format consistent across your credential population.
