The perfect embedded fingerprint module for YOU!

Lumidigm M310 fingerprint module is designed for those who need a biometric technology or solution that simply works where other competitive alternatives often fail.

Renowned Technology

Lumidigm’s patented multispectral imaging technology fills the performance gap and makes security easier. It is easy to incorporate. Lumidigm fingerprint sensors produce up to 20% better results than conventional biometric solutions. It has the capability to enroll fingerprints from rough fingers as well. It works in every environment.

Built for Business

Designed for businesses, the Lumidigm M-series fingerprint sensors are durable. The performance of these sensors helps your enterprise collect the best quality fingerprint images adding value to your enterprise. Thanks to the extraordinary performance of Lumidigm that delivers the best return on investment.


Lumidigm fingerprint sensors use multispectral sensors to capture high quality images even in the cases such as genetics, age, dirt, finger placement, or environmental conditions where it is hard to distinguish fingerprint points. It can easily capture fingerprints of all people including the people who have problems in their fingerprints enrollment. It increases user satisfaction by increasing the fingerprint enrollment rate while reducing the failure counts.

Fast and Reliable

Lumidigm M-Series fingerprint sensors are super-fast and easy to use. It makes the life easier by providing a convenient and lightning-fast biometric authentication solution that owns the capability to capture best fingerprints in varied environmental conditions. Whether you are young or old, Lumidigm M-Series fingerprint sensors will enroll fingerprints on the first go. These sensors turn biometric authentication into a practical reality.

Image quality

To ensure fingerprint reliability, it is must to have high quality fingerprint images. Lumidigm fingerprint sensors capture high quality fingerprint images offering the most accurate and reliable fingerprint biometric. These sensors use Lumidigm’s patented multispectral imaging system. This system uses multiple wavelengths of light to enroll both external fingerprint and internal fingerprint. In case, mostly happen with old people, the external fingerprint is obscured, multispectral imaging system uses the internal fingerprint data to capture clear, clean images in any environment. With such high quality, it helps reducing the system ownership cost by offering high return on investment, reducing users’ frustration, and reducing the management enrollment.

Liveness detection

Lumidigm fingerprint sensors are designed to offer the best protection against fake and spoof fingerprints. This has been made possible by the liveness detection technology used in the Lumidigm sensors. Lumidigm keeps enhancing its fingerprint detection capability to provide you the most accurate and secure fingerprint sensors.

Lumidigm M310 Benefits

Patented multispectral imaging used in Lumidigm makes it the most accurate, secure, and convenient biometric authentication sensors available on the market. This multispectral imaging is available only in the Lumidigm® products and solutions providing them the capability to enrol fingerprints under varied circumstances, ages, and environmental conditions.

Lumidigm® multispectral imaging is an advanced technology that is purposely designed to ensure highest fingerprint enrolment rate regardless of environmental conditions and age of the person. This technology uses multiple spectrums of light and advanced optical techniques in order to capture unique fingerprint characteristics from external and internal surfaces of the skin. This is beneficial because in many cases the upper surface does not have fingerprints. In such cases, fingerprints captured from the inner skin help perform the biometric authentication.

With this advanced technique, users are able to mitigate the traditional system vulnerabilities against common environmental and demographic conditions:

Dry conditions

Fingers can be dry due to different reasons like climate, natural skin behavior, frequent washing of hand, air travel etc. Enrolling high quality fingerprint images from dry fingers are hard, but Lumidigm® multispectral imaging has made it simple and accurate.

Diverse demographics

Diverse demographics often make it difficult to capture fingerprints despite the fact every human is unique. Lumidigm® multispectral imaging has the capability to authenticate anyone in diverse demographics regardless of age, lifestyle, and ethnicity.

Wet conditions

Hands can be wet due to environmental conditions (like in naturally damp places) or a setup (like spa). Lumidigm® multispectral imaging makes Lumidigm sensors to enroll high-quality fingerprints even in web conditions.

Rugged conditions

Lumidigm® multispectral imaging makes the Lumidigm sensors always ready to capture high quality fingerprints. Whereas traditional fingerprint sensors require people to wash and lotion their hands, Lumidigm sensors can enroll fingerprints in any condition and at anywhere like office, agricultural field, or construction site.

These environmental conditions are resolved by Lumidigm® multispectral imaging. Lumidigm fingerprint sensors with Lumidigm® multispectral imaging have proven to be the best technology in the biometrics industry.
