Frequently Asked Questions
Do I need the dual-tech version instead?
Only if some of your doors still use 125 kHz proximity readers. If your facility is fully on 13.56 MHz smart readers, the single-frequency 50L2-LU4 is the simpler, more cost-effective choice.
What is the digital manifest?
A file included with each pack listing every credential's unique badge ID, which you upload directly into your access control system by CSV instead of entering cards manually.
Is this card locked to Wavelynx readers only?
No. LEAF Universal is an open standard designed to work across the LEAF Community ecosystem of compatible readers and platforms, not just Wavelynx hardware.
How are the 25 cards packaged?
Wavelynx manufactures LEAF Universal credentials in factory-sealed packs of 25.
