Section 4 - Operation

Background

In organizations where users simultaneously work on multiple
computer environments, the use of smart cards to secure logons
and applications (such as email encryption) generates a costly and
administrative-intensive overhead.
Due to the fact that a dedicated smart card and smart card reader
have to be purchased, programmed and installed on both per user
and computer bases multiplied by the number of computers and
users in the organization, the TCO and administrative effort
required to support such environments is extremely high.
For example, an employee that has to access 3 computers
simultaneously would need to have 3 smart cards, one for every
computer environment (domain) plus 3 smart card readers, each
reader connected to a separate computer.
EMERSON MDR Solution
EMERSON developed the Secure Multi-Domain Smart Card Reader
(MDR) technology to provide a simple and yet secure solution to
this common problem.
The EMERSON Multi-Domain Smart Card Reader (MDR) is a single
secure smart card reader which connects simultaneously to multiple
computers thus allowing a user to utilize a single smart card while
working securely on multiple computer environments at the same
time.
