HID Global's iCLASS Seos smart cards are based on a secure, open technology to manage and authenticate identities. The cards primarily address the need for securing identities for the physical access control solution (PACS) market but are also provisioned to support other applications, including One-Time Password authentication (OTP) for login into networks and other IT resources. iCLASS Seos cards are ideal for organizations with stringent security requirements for their credential solution, as well as enterprise and government organizations looking for a cost-effective solution. The cards deliver superior data integrity and privacy protection by leveraging the advanced cryptographic algorithms. iCLASS Seos cards also utilize a secure messaging protocol to protect data transmission with the off-card applications providing strong authentication mechanisms to protect the communications between card and reader.
