From Biometrics to Smartphones, the Future of Access Control

By Franco Faraudo

We’ve all become pretty comfortable with biometrics, whether it’s unlocking our phones with our faces or breezing through airport security with an eye scan. Now, it’s time to bring that same ease to our workplaces. Imagine allowing employees to walk into the office, wave their hand, and gain instant access—no more hunting for access cards or PINs. It’s not just about convenience, it’s also a step up in security because unique biometric data can’t be easily replicated. But this new technology also carries with it risks and not everyone is on-board with buildings and employers collecting this sensitive biometric data.

Access Control Technology

Access Control’s Vital Role in Building Automation

Access control in building automation not only offers security; it provides detailed information about occupancy that allows for automated temperature, lighting, and air quality adjustments.

2024’s Real Estate Outlook Shaped by Cutting-Edge Technologies

The commercial real estate market is adapting to a hybrid work model, with fluctuating occupancy and tenant needs. This is driving demand for technology that can track occupancy, enable flexible access across multiple locations, and improve building efficiency and security. While widespread adoption is not immediate, forward-thinking companies are already planning to implement these solutions.

Adopting Mobile Access for Buildings Just Got a Lot Easier

Mobile phones are replacing physical objects like wallets and keys, and a new standard called Aliro will soon allow phones to unlock most doors, requiring buildings to upgrade their systems for continued use.

Is Biometrics the Future of Access Control?

Biometric technology is being used more and more for building access control, replacing traditional keys and keycards. Fingerprint scanning and facial recognition are the most common methods, but other options like palm scanning and voice recognition are also being explored. While biometrics offer convenience and security, there are concerns about privacy, cost, and legal issues. Despite these challenges, biometrics are likely to become the norm in building access control in the future.


Kastle has announced the first interoperable physical access control system that gives building owners the ability to future-proof their access control technology today with the greatest flexibility and interoperability for years to come.

See how we’re striving to create a world where the same open-standard mobile credential gives users seamless access to all the places they live, work, and play.
