Author: Brian Rhodes, Published on Jan 14, 2015

Given the variety of types available, specifying access control readers can be a daunting process. However, focusing on a few key elements will help you arrive at the right product no matter which system you are using. These include:

  • Credential Type
  • Mounting Surface
  • Read Range
  • Infrastructure Requirements
  • Protocol Support (Wiegand vs. OSDP)

In this note, we address these attributes, explain how they are different, and help users understand which reader is the ideal choice for their application.
