Common Questions Before Ordering
- Will this reader work with my existing HID cards?
Compatibility depends on credential technology and reader configuration. Existing HID Prox®, iCLASS®, Seos®, MIFARE®, or DESFire® credentials should be reviewed before ordering. - Can I use this reader with my current access control panel?
The Signo 40 supports Wiegand and OSDP communication protocols, but compatibility should always be confirmed with your controller or panel. - Is this the same size as the HID Signo 20?
No. The Signo 40 is the larger wall-mount version while the Signo 20 is a slimmer mullion-style reader. - Do I need new credentials when upgrading?
Not always. Some installations can continue using existing credentials while others may choose to upgrade to smart cards or mobile access solutions. - Looking for a pigtail connection version?
