HID has released their first access reader to use Lumidigm optical sensors, that touts it 'works with anyone, anytime, anywhere'.
We bought and tested the unit to see if it lives up to the claims.
Inside, we answer the following questions:
- How well does the fingerprint reader work on dirty, oily, greasy, and wet fingers?
- Does saltwater spray on the reader and sensor impact performance?
- What types of wired connections and power is needed?
Our test also evaluated key performance parameters including:
- The problem with the RB25F fingerprint enrollment process
- How well the unit communicates using OSDP and Wiegand
- The new software application needed to configure the unit
- HID Mobile Access compatibility
- Which 13.56 MHz credential formats are supported
Testing Dirty Prints
To test fingerprint reading performance, we subjected a finger to different types of soiling.
For testing, we used five different methods of determining read performance apart from ideal 'clean' fingerprints. Testing checked:
Soil/Mud: Common dry and slightly damp topsoil was applied
Water: Both finger and sensor were subjected to potable water
Oil: A thin vegetable oil was used to coat finger skin
Grease: A heavy paste was used to 'build-up' and fill fingerprint features, but was translucent
Saltwater Spray: Finally, a mild saline solution was sprayed onto the reader and sensor to determine if slightly cloudy/turbid liquids impacted performance
We also benchmarked those individual results against a 'control' finger that was clean and dry.
