iClass is a type of contactless smart card technology developed by HID Global, a leading provider of identity and access management solutions. Here are the differences between the various iClass technologies you mentioned:


This was the original iClass technology released in 2002. It uses 13.56 MHz frequency for contactless communication and offers secure data transmission with encryption.


Although iClass ELITE or SE ELITE doesn’t offer the same flexibility and security as Seos, iCLASS SE credentials can be considered a more powerful option than standard iCLASS due to a higher data storage capability.

  • It also gets an SIO (Security Identity Object). This makes the card less vulnerable than other 13.56MHz technologies.
  • iCLASS SE can be combined with older technologies such as MIFARE Classic.


HID iCLASS ER is an upgrade to Elite/SE which only allows for SIO object.

  • A software-based infrastructure and enhanced cryptography
  • A data model for storing and transporting identity information in a single object


HID iCLASS Seos supersedes legacy and existing credential technologies by providing these key benefits:

  • A software-based infrastructure and enhanced cryptography
  • Unrivaled data and privacy security that may be utilized for purposes other than access restriction.
  • Dual-identity and mobile credentials are examples of cutting-edge capabilities.
  • In comparison to other credential technologies, best-in-class cryptography
  • Seos is software-based and independent of the chip on card, allowing for new levels of form factor flexibility, including application on mobile devices, smart cards, tags, and other devices.
  • SEO may be utilized to provide customized solutions for a variety of industries, including education, hotels, and government organizations.


iClass SEOS Essential: This is a more affordable version of iClass SEOS designed for use in cost-sensitive applications. It offers basic security features such as encryption and authentication, but with reduced memory capacity compared to the standard iClass SEOS technology.
