Selecting Access Control Readers Tutorial

Author: Brian Rhodes, Published on Nov 09, 2017

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 factors are:

  • The Basic Reader Types: Contacless, Barcodes, Keypads, and Biometrics
  • Quick Overview Of Contactless Frequencies and Formats
  • How Mounting Surfaces Impact Selection
  • Why Establishing Contactless Read Range Is Crucial
  • Awareness Of Infrastructure Requirements Like Power and Connectivity
  • 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.
