What advantages do mobile access control systems offer over traditional cards or keys?

Last updated: March 25, 2026

In an increasingly connected world, mobile technology is transforming the way we manage building security. Smartphone-based access control systems, which allow doors to be opened using smart devices, are gaining ground as a more flexible alternative to RFID cards or traditional keys.

But what specific benefits do these new solutions offer, and why are they revolutionizing corporate and residential security?

This paradigm shift is no accident. For decades, metal keys and plastic cards have been the gatekeepers to our spaces. However, in the digital age, their limitations in terms of flexibility, control, and adaptability have become apparent.

At TESA ASSA ABLOY, we are driving this evolution through the SMARTair ecosystem, which integrates advanced access control solutions, including Openow, our mobile access solution. Thanks to these technologies, we are able to meet the demands of an environment that requires immediacy, intelligent management, and a much more robust level of security.

This transition reflects how life, work, and security now come together in a device we always carry with us, making access control a more convenient, connected, and secure experience.

One of the major benefits of mobile credentials is their superior level of security. Physical cards can be easily lost or even duplicated. In contrast, a mobile credential is protected by the same security measures as the smartphone itself (PIN, fingerprint, or facial recognition) and is transmitted using advanced end-to-end encryption.

The most significant advantage is the ability to respond immediately. If an incident occurs, credentials can be revoked or modified instantly and remotely via the cloud platform. This online management eliminates the risk of unauthorized access and minimizes response times. In addition, our systems enable detailed audits with full access traceability.

Solutions such as SMARTair Wireless Online allow you to monitor access in real time and immediately lock or unlock a door in the event of any incident—something that is impossible with physical keys or conventional cards.

For administrators, mobile access control simplifies operations, leading to increased efficiency and cost savings. The need to issue, print, and distribute physical cards is eliminated. The entire credential lifecycle is managed through a centralized cloud-based platform.

This digitization results in a significant reduction in costs associated with hardware, as well as time spent on management and maintenance. The flexibility offered by cloud-based management makes it possible to grant temporary access to contractors or schedule specific access times for employees with a level of granularity that traditional keys never allowed.

In addition, TESA ASSA ABLOY’s SmartAir and eCLIQ systems allow for the integration of electronic locks, cylinders, and mobile readers within the same environment, enabling comprehensive management through a single system.

Convenience is the most obvious benefit for the end user. The smartphone has established itself as the only universal credential, offering features such as hands-free access—ideal in situations where the user is carrying equipment.

The experience these systems offer is inherently more intuitive and technologically advanced. Furthermore, it paves the way for advanced integration with other digital solutions, such as smart elevators or parking systems.

A clear example of this improvement can be seen in the hotel industry. Modern establishments, such as the innovative Kora Green City aparthotel in the Basque Country, are adopting these solutions. Using technologies such as TESA ASSA ABLOY’s Openow app, guests can check in on their own and receive a virtual key directly on their smartphone before arriving. This streamlines the guest check-in process and reduces the operational workload for hotel staff.

Other obvious applications can be found in educational or corporate settings, where TESA SmartAir has enabled students or employees to access different areas of the campus or office building using a single mobile credential, dynamically adapting to their assigned permissions.
