The Wavelynx EV3 8K ISO Card (P/N 50L8) is a 13.56 MHz MIFARE DESFire EV3 contactless smart card with expanded 8K memory, sold here as a bulk pack of 100 factory-programmed credentials.
The 50L8 shares the same high-frequency (13.56 MHz) MIFARE DESFire EV3 platform as the rest of Wavelynx's EV3 card line, with double the onboard memory of the 4K variant. That extra capacity makes it a good fit for deployments that combine access control with a second application on the same credential cashless payment, secure print release, or time-and-attendance without needing a second card. Every card in this pack of 100 is factory programmed to your encryption keys, bit format, facility code, and ID range before it ships.

Frequently Asked Questions
Why choose the 8K card over the 4K version?
The extra memory leaves room to add a second application later — such as cashless vending, secure printing, or time-and-attendance — without reissuing credentials.
Is the 50L8 dual-frequency?
No, it's a single-frequency 13.56 MHz card. For a version that also reads 125 kHz proximity, see the Dual Tech EV3 8K + Prox ISO Card (50M8).
What encryption does this card use?
The MIFARE DESFire EV3 chip is EAL 5+ certified and supports AES-128 encryption, along with custom key options for your deployment.
How are these cards packaged for shipping?
Cards ship in a single pack of 100, factory-programmed and ready to enroll — no individual unboxing or on-site encoding required.
Standardize your access credentials with the Wavelynx EV3 8K ISO Card, available in bulk packs of 100 for organizations that need room to grow.
