Contactless Access Credentials Guide

Author: Brian Rhodes, Published on Sep 10, 2015

Few access topics are as complicated as contactless credentials. Chosing the correct one can be the difference between a secure facility and wasting big money. Understanding how they operate and what their specifications mean is a big challenge.

In this update, we cover the basic elements needed to specify the right contactless credentials everytime, including:

  • HID vs. NXP Credential Formats
  • 125 kHz vs. 13.56 MHz Frequencies
  • Facility Names
  • Facility Codes
  • Card ID/Serial Numbers
  • ISO 14443A vs. 14443B
  • Form Factors

Good information. Could be a bit more basic for readers that lack technology vocabulary and still learning it.

I agree.

Even a list of acronyms at the beginning of this article or in its own article would of been a nice resource. And maybe a "bird's eye view" article of what the components are to a complete system and then zoom in on the reader component.

Hello Keith

I strongly believe in having a bird’s eye view of access control systems and then narrowing down on the different aspects and ending with tying them up again will be a simpler approach.

This approach is also good because it has got me studying hard and discovering more personally.

It was quite interesting.

Great information but still a little more technical than I am used to. I usually troubleshoot software for card access systems, but this has been a great overview of how the system actually works!

Having been involved already in being asked by prospects whether their existing cards would work with our readers, I was hoping for more clarity on the issue, but it sounds like that's hard to get due to the complexity of the standards and formats.

This is a fruitful Contactless Access Control illustration. The article clearly explains the concept behind the structure and the operation of the contactless credential. I appreciate the info
