About ievo biometrics

ievo solutions are designed to bring next generation biometric technology to the world of access control. Biometric systems offer benefits for both security and convenience. It’s our mission to bring those benefits to as many worldwide users as possible. We believe that biometric access and entry solutions can and should be easy to install, simple to use, and robustly secure. ievo solutions include both fingerprint recognition and facial recognition technology.

We’re proud to manufacture biometric products that use best-in-class components to ensure high performance. In addition, we build a wide range of extra security features into our solutions to keep user data as safe as possible. ievo biometrics are the ideal third-party biometric solution for access control and time & attendance systems. We’re already integrated into market-leading solutions, and our mid-point software isync makes new integrations simpler than ever.


Biometric Fingerprint Readers

ievo biometric fingerprint readers combine robust security with high performance. Designed as a third-party solution for integration into access control and time & attendance solutions, ievo readers are both easy to use and equipped with best-in-class technology.

The core component of the ievo ultimate™ reader is its multi-spectral imaging sensor. This world-class technology uses nine different light sources to penetrate deeper into the surface of the fingerprint. As a result, the captured images are extremely accurate and highly reliable.

In terms of data security, ievo readers are inimitable. When a user first presents their finger to the reader, the multi-spectral scanner produces a digital image of the print. Tiny, unique features called minutiae are identified – up to 100 of them. The pattern and structure of the minutiae are converted via an advanced proprietary algorithm into a template saved on the accompanying Interface Board. The original image is permanently erased, and cannot be reproduced using backwards-engineering.

Facial Recognition

Facial recognition technology utilises the unique shapes, sizes, and structures of people’s facial features to verify their identity. Similarly to fingerprint recognition, the pattern of these features is converted into a digital map of the face. This digital template is then compared against the saved database to establish whether a match exists or not.

In access control, facial recognition offers ultimate convenience and unparalleled speed. iface™ by CDVI identifies and authenticates faces in just one second. And what’s more, the user doesn’t have to remember a PIN, carry a card, or wear a lanyard. There’s nothing for them to forget at home or have stolen. In situ, facial recognition can also make life much easier, especially in workplaces where it’s not always easy to have a hand free to operate another kind of access control system. Think warehouses, manufacturing plants, care homes, and hospitals.

Businesses & End Users

More and more businesses are adopting biometric authentication methods for staff. In 2022, 79% of companies in the USA were using some form of biometrics. Why? Because of the inherent benefits to security, convenience, and tracking that biometrics offer.

Biometric access control in your business means:

  • no more cards or fobs that are constantly lost, stolen, or damaged
  • no more card cloning risks or people tailgating through access points
  • better data security and resistance to cyber attacks
  • more reliable tracking of entry and exit at access points

Why Biometrics?

Better security

Biometric data is unique to individuals, making it extremely difficult to lose, steal, or clone. This inherent uniqueness means security is more robust and resilient.

More compliance

Make card sharing is a thing of the past. With biometrics, you know that only authorised individuals can utilise their own biometric features.

Less admin

Over time, a biometric solution requires less admin time and no ongoing costs for replacing lost, stolen, or damaged cards/fobs.

Data protection

There is no data stored on the ievo fingerprint reader heads at all. So even if the product is vandalised or stolen, the data is safe.

High reliability

We use best-in-class components in ievo products to ensure that they work well and last longer. ievo offers solutions for indoor, outdoor, and even harsh weather conditions.

Seamless integration

Off-the-shelf integrations with multiple major access control manufacturers create comprehensive building management systems.
