Choosing the correct one can be the difference between a secure facility and wasting significant money. Understanding how they operate and what their specifications mean is a big challenge.

In this guide, we cover the basic elements needed to specify the right contactless credentials, 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
