The Wavelynx LEAF Universal Dual Tech Card (P/N 50M2-LU4) is a composite smart card combining MIFARE DESFire EV3 (13.56 MHz) with 125 kHz proximity, sold here as a bulk pack of 25 factory-programmed credentials from Wavelynx's open, interoperable LEAF Universal line.
LEAF Universal is Wavelynx's open credential standard, built so a single card isn't locked to one reader manufacturer. The 50M2-LU4 pairs MIFARE DESFire EV3 (13.56 MHz) with 125 kHz proximity in one composite PVC-PET card, giving you dual-frequency coverage plus interoperability across the LEAF Community ecosystem of readers and platforms. Each credential carries a unique badge ID with no duplication risk, and every pack arrives with a digital manifest that loads straight into your access control system by CSV no manual data entry required.Â

Frequently Asked Questions
What makes LEAF Universal different from Wavelynx's standard EV3 line?
LEAF Universal credentials are built around an open standard designed for interoperability across the LEAF Community of reader and platform partners, with added enrollment tools like the digital manifest â rather than being tied to one proprietary format.
What is the digital manifest, and how does it help?
Each pack includes a digital manifest â a file listing every credential's unique badge ID â that you upload directly into your access control system by CSV, removing the need to manually enter each card.
Is this card dual-frequency?
Yes. The 50M2-LU4 reads both 125 kHz proximity and 13.56 MHz MIFARE DESFire EV3, making it suitable for sites running both technologies during a reader upgrade.
How are the 25 cards packaged?
Wavelynx manufactures LEAF Universal credentials in factory sealed packs of 25.
