Questions
HID iCLASS Questions
Does xSERVA read HID cards?
Yes. UltraPASS-Door reads HID iCLASS and HID Prox. Send us a sample card and we confirm the format before you commit.
Do I have to re-issue my HID cards?
Not on day one. Cards keep working, and you retire them gradually.
Can HID cards pair with face recognition?
Yes. Pair a card with a face or PIN on doors that need two factors.
