The RS40N-4 four-port secure multi-domain smart card reader (MDR) enables the use of one smart card to logon to four computers simultaneously.
In organizations where users simultaneously work in multiple computer environments, the use of smart cards to secure logons and applications (such as email encryption) generates a costly and administrative-intensive overhead. Since a dedicated smart card and smart card reader must be purchased, programmed and installed on both a per user and computer basis, 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 4 computers simultaneously would need to have 4 smart cards, one for every computer environment plus 4 smart card readers, each reader connected to a separate computer.
HSL developed secure Multi-Domain smart card Reader (MDR) technology to provide a simple yet secure solution to this common problem. The HSL RS40N-4 Multi-Domain smart card Reader (MDR) is a single secure smart card reader that connects simultaneously to up to four computers, allowing a user to utilize a single smart card while working securely in multiple computer environments. Removing the smart card from the MDR immediately de-associates the MDR from all coupled PCs. As a result, smart card-aware applications will notice the smart card's absence and respond accordingly.
- Reduce overall smart card operational costs; buy less smart cards and less readers.
- Minimize smart card administrative overhead. Use a single smart card for multiple computers.
- Increase security by auto-logoff/lock all computers the user is working on upon smart card removal.
Compliant with NIAP Common Criteria PP4.0 PSD Protection Profile. BAA and TAA compliant.

High Sec Labs RS40N-4 Features
- First and only - The only smart card reader available today that can interface with multiple isolated computers. Based on unique technology and patents.
- Compatibility - The MDR design relies on Identive (formally SCM) readers. It is by far the industry's most popular and compatible smart card reader. The product is supported by most operating systems in use today.
- All firmware is in ROM (Read Only Memory).
- Cost effective - This product was designed to provide an affordable solution for agencies and organizations. Product cost is easily justified once compared with issuing and maintaining multiple cards for each user.
- Ease of use - The MDR automatically switches between channels. The user needs only minimal training on the device's operation.
- Tamper Evident Label - Special holographic tamper-evident labels provide clear visual indication that the product was tampered with or opened
- Highest security by design -The only smart card reader designed from its early stages to support high security isolation applications.
High Sec Labs RS40N-4 Security Features
- No shared circuitry across channels other than the user card. Each channel uses its own card reader circuitry
- Power sub-system is divided and fully protected from power signaling attacks
- Secure card removal messaging function with backup circuitry
- Audible warning if card is inserted and no active session available for more than 60 seconds
- Audible warning if card is partially inserted for more than 15 seconds
- Holographic tamper-evident labels to detect enclosure tampering
- Sealed plastic design to prevent physical tampering
