In many companies, access control and time tracking still exist as separate systems. While access control regulates access to buildings and sensitive areas, time tracking is used to document working hours. Both systems fulfill important tasks – but they only develop their full potential when access control and time tracking are combined.
Historically evolved IT structures are not uncommon, especially in SMEs. Different solutions from different providers have been introduced, expanded or adapted over the years. This often results in isolated solutions that fulfill their purpose but only communicate with each other to a limited extent.
➡️ The result: processes are unnecessarily complicated, data is maintained multiple times and potential is wasted. Companies that intelligently combine access control and time tracking, on the other hand, create a central basis for more efficient processes, better transparency and greater security.
Why are separate systems becoming increasingly problematic in practice?
At first glance, separate systems often seem sufficient. Access control regulates access to the building, time tracking documents working times. In technical terms, these seem to be clearly separate areas of responsibility. In day-to-day operations, however, this gives rise to numerous challenges.
A central problem is the duplicate data maintenance. Employees often have to be created, updated or deactivated in several systems. If departments, authorizations or working time models change, this information has to be adjusted several times. This not only costs time, but also significantly increases the susceptibility to errors.
Added to this is a lack of transparency. If access data and working hours are recorded separately, there is no uniform view of attendance and use of resources. Companies then know who has clocked in, but not necessarily who is actually in the building or which areas are being used.
This is particularly critical in larger companies with several locations or in the event of an evacuation, for example in the event of a fire. Different data statuses can quickly lead to Inconsistencies and make evaluations difficult. Managers and HR departments have to gather information from various sources in order to obtain a complete picture.
There are also disadvantages from a security and compliance perspective. For example, if an employee is deactivated at short notice or leaves the company, authorizations often have to be adjusted manually in several systems. If this is not done consistently, potential security risks arise.
In addition, separate systems make it more difficult to comply with regulatory requirements. Companies increasingly need to be able to prove who had access when and what working hours were actually worked. Without an integrated database, this traceability becomes much more complex.
Two systems, one goal: transparency and control
Access control and time tracking essentially pursue a similar goal: they create transparency about who is in the company and when they are working. If the two areas are combined, the result is a much more efficient overall process.
Access events and working times are interlinked and form a common database. This gives companies a consistent view of attendance, working hours and access rights. This not only reduces administrative work, but also improves the quality of the information available.
Decisions are based on up-to-date and complete data instead of isolated individual pieces of information.
Efficiency gains through standardized systems and RFID media
One of the main advantages of access control and time tracking combination lies in the use of a common technical infrastructure. The use of a standardized RFID medium, such as an employee card or a chip, is particularly relevant for both areas of application.
In practice, this means that employees only use one medium for access and time booking. This makes processes much simpler and more consistent. Companies do not have to manage separate cards, tokens or systems, which reduces both administrative effort and complexity.
At the same time, user-friendliness is improved considerably. Employees work with a standardized system, which reduces training costs and sources of error. HR, IT and facility management are also able to centrally manage authorizations and master data.
However, it is important to make a clear distinction between access events and the actual recording of working time. Automatically equating “entering the building” and “start of working time” can be problematic in practice. For example, time spent in the building outside of working hours, breaks, meetings or external activities can lead to inaccuracies. This is why modern solutions often rely on a common RFID medium, but nevertheless on deliberately separate processes for access booking and time booking. As a result, companies benefit from a consistent system landscape without losing the necessary accuracy and traceability when recording working time.
In addition, a shared RFID system simplifies administration considerably. Authorizations, roles and access can be controlled centrally and adapted more quickly in the event of changes. If an employee leaves the company, in many cases the deactivation of a single medium is sufficient to block both access and time recording functions. This is an important advantage for SMEs in particular: less administrative work, greater process security and a modern, integrated user experience for employees and managers.
Higher data quality and better evaluations
The combination of access control and time tracking significantly improves data quality. As both systems work on the same database, there are no inconsistencies between attendance and booked working times.
This gives companies completely new possibilities for analysis. For example, capacity utilization of locations or work areas can be better evaluated. Patterns in attendance or shift changes also become more transparent.
These findings are not only relevant for HR. They also support management, facility management, safety officers and operational managers. This transparency is becoming increasingly important, especially in times of hybrid working models.
More security in the company
In addition to efficiency, security also plays a key role. Access control systems ensure that only authorized persons are granted access to certain areas. In combination with time tracking, this creates additional added value.
Companies not only know who theoretically has access, but also who is actually in the building. This can be crucial in the event of evacuations or emergencies. Attendance lists can be created in real time and provide a reliable basis for security measures.
In addition, unusual activities such as access outside regular working hours or access to sensitive areas can be detected more quickly.
Compliance, NIS2 and KRITIS: Why integrated systems are becoming increasingly important
The integration of access control and time tracking also offers clear advantages in terms of legal and regulatory requirements. Companies must increasingly be able to prove that working times are correctly documented and that access to buildings, sensitive areas or critical infrastructures is recorded in a traceable manner.
This is no longer just about traditional labor law requirements. With new regulatory requirements such as the European NIS2 Directive and increasing requirements in the KRITIS environment, security and documentation obligations are becoming much more important.
Companies with critical processes, sensitive data or relevant infrastructure in particular must ensure that physical access is controlled, logged and traceable if necessary.
➡️ These include, for example, the questions:
- Which people had access to certain areas and when?
- Who was in the building at what time?
- Which authorizations were active?
- Have safety guidelines been adhered to?
Separate systems make this traceability considerably more difficult. Data is stored in different applications, evaluations have to be merged manually and consistent audit trails are often missing.
Integrated solutions create a much better basis here. Access events, authorizations and time bookings can be documented centrally and evaluated in an audit-proof manner.
✅ This creates consistent evidence for:
- Internal audits
- Compliance audits
- Safety analyses
- External certifications
- Regulatory controls
This aspect is becoming increasingly important, particularly in the context of NIS2. The directive significantly increases the requirements for cyber security and risk management – including for many SMEs. In addition to IT security, physical security is playing an increasingly important role, for example through controlled access to critical areas and traceable security processes.
KRITIS-related companies or suppliers of critical infrastructures are also facing increasing requirements. Integrated systems help to centrally manage security and compliance processes while reducing administrative effort.
This gives companies a double advantage: greater security on the one hand and significantly better verifiability vis-à-vis authorities, auditors and business partners on the other.
Basis for integrated workforce management
The combination of access control and time tracking is often the first step towards more comprehensive workforce management. As soon as both systems are integrated, other areas can be usefully added , such as
Staff scheduling, absence management, resource planning or electronic sick notes (eAU). This creates a central platform for operational and strategic decisions. Companies not only gain
efficiency, but also create the basis for further digitalization projects.
Conclusion: More than the sum of individual systems
The combination of access control and time tracking offers companies far more than just technical advantages:
It reduces complexity, improves data quality and creates the basis for more efficient processes, greater security and better traceability.
Medium-sized companies in particular benefit from integrated solutions because they conserve resources while increasing transparency and process reliability. They also create a central basis for future digitalization and workforce management strategies.
In the course of integration, however, not only the software but also the existing hardware landscape should be considered. Many companies already have RFID readers, ID cards or access components that could, in principle, continue to be used. Adopting existing hardware can reduce investment costs and significantly simplify migration projects.
At the same time, however, careful examination of the RFID technologies used is crucial. Older or insecure RFID standards often no longer meet today’s IT and access security requirements. Against the backdrop of increasing regulatory requirements – such as NIS2 or KRITIS-related security requirements – companies should therefore evaluate whether existing components can continue to be operated in a future-proof manner.
A security assessment of the existing infrastructure is particularly recommended for older RFID media and reader systems. Companies should check whether the technologies used meet current security standards and can be protected in the long term.
➡️ The decisive question is therefore no longer whether access control and time tracking should be combined, but how companies can take the next step as efficiently, securely and sustainably as possible.
