The Wavelynx Dual Tech EV3 8K + Prox ISO Card (P/N 50M8) is a dual-frequency smart card combining 125 kHz proximity with 13.56 MHz MIFARE DESFire EV3, sold here as a bulk pack of 100 factory-programmed credentials.
The 50M8 is built for organizations mid-migration from legacy 125 kHz proximity access control to modern encrypted smart credentials. One card reads at both frequencies, so a single credential works across your existing proximity readers and any new 13.56 MHz MIFARE DESFire EV3 readers you roll out no need to issue two cards or run parallel credential systems during the transition. With 8K of memory on the smart-card side, there's also room for a second application beyond access control. Every card in this pack of 100 ships factory-programmed to your encryption keys, bit format, facility code, and ID range.

- Organizations that can't afford downtime or dual-badge workarounds during migration
- Facilities wanting a future-ready card that still works with legacy hardware today
Frequently Asked Questions
Why would I need a dual-frequency card instead of a smart-only card?
If some of your doors still use 125 kHz proximity readers while others have been upgraded to 13.56 MHz smart readers, a dual-tech card lets one credential work at every door during the transition.
What's the difference between the 50M8 and the 50M4?
Both combine 125 kHz proximity with 13.56 MHz MIFARE DESFire EV3. The 50M8 carries 8K of memory on the smart-card side; the 50M4 carries 4K.
Will this replace my proximity cards immediately?
You can issue the 50M8 as a direct replacement for existing proximity cards â it will work on your current prox readers on day one, and on any new EV3 smart readers as you install them.
Are these cards printable?
Yes, the composite PVC/PET surface supports standard direct-to-card printing for photo IDs and branding.
Keep every door working during your access control upgrade with the Wavelynx Dual Tech EV3 8K + Prox ISO Card, available in bulk packs of 100.
