HID Signo readers are commonly associated with HID iCLASS and Seos credentials, but many Signo reader profiles also support additional high-frequency technologies including MIFARE® Classic, MIFARE® DESFire® EV1, EV2 and EV3, as well as select low-frequency proximity credentials. This gives organizations more flexibility when choosing cards, fobs and mobile-ready credential platforms for access control.
Not Limited to iCLASS
While HID strongly promotes iCLASS and Seos technologies, Signo readers can often be configured to read other credential types as well, depending on the reader model, profile and access control system configuration. iCLASS is not the only credential you can use in your Signo reader. You do have options!
Credential Savings
MIFARE and DESFire credentials can provide a more cost-effective alternative to proprietary HID smart credentials. The iCLASS 2000PGGMN sells for $4.71 each. The MIFARE 1K Classic sells for $1.59 each. The DESFire EV2 ISO sells for
$2.29 each.
Step into the Future
MIFARE and DESFire operate at 13.56 MHz, which is the more modern frequency, and offers more secure options. ID Enhancements, Inc. offers scaleable credential solutions for entering this modern platform.

Using the DESFire CSN as the Credential Number
DESFire cards are capable of advanced encrypted smart card applications, but many everyday access control systems do not use the full secure application layer. In many real-world installations, the reader simply outputs the card's CSN, UID or serial number to the access control panel, and that number is used as the credential identifier in the software database.
In these cases, the DESFire card is being used more like a high-frequency serial number credential rather than a fully managed encrypted smart card. This approach can reduce complexity, avoid advanced key management and still give customers access to a modern 13.56 MHz credential platform at a reduced cost.

DESFire Usage: Two Common Approaches
Important Compatibility Note
Reader capability does not automatically guarantee system compatibility. The HID Signo reader profile, output format, access control panel, software settings and credential numbering structure must all be compatible. Some systems may use Wiegand output, others may use OSDP, and some deployments may be locked into specific credential technologies or secure profiles.
MIFARE Classic
A widely used 13.56 MHz credential option for cost-conscious access control applications. Hotels are a perfect example of a MIFARE credential environment.
MIFARE DESFire EV1/EV2/EV3
A modern smart credential technology that can be used for simple CSN output or advanced encrypted applications. Commonly used in corporate, financial and military installations.
HID iCLASS SE / SR
HID smart credentials are commonly deployed in new installations or recommended by HID-integrating security dealers.
HID Seos
HID's high-security credential platform designed for mobile credentials and modern secure applications. Utilized wherever mobile technology convenience is a preference.
125 kHz Proximity
Proximity technology is supported for backward compatibility in many installations, and is still commonly used today.
Bottom Line
HID Signo readers can offer more credential flexibility than many customers realize. For organizations that simply need a reliable credential number, MIFARE or DESFire CSN output may provide a practical, lower-cost alternative to higher-priced iCLASS credentials. For higher-security environments, DESFire can also support advanced encrypted applications when properly programmed and managed.
