Everything you need to get the most out of ProjectAssistant. From attendance to documents, ID checks, and scheduling.

Frequently Asked Questions

How does clock-in via NFC and QR work?

Clock-in is done via NFC TagPoints or scannable QR codes assigned per project or zone. The app verifies location, time, and project permissions, and syncs directly via SignalR.

How does document control work?

Each document type falls into a sector and country profile. Employees are automatically linked to the correct documents based on their role, company type, and project. ProjectAssistant monitors expiration, validation status, and reassessment.

How does ID check via NFC work?

The app reads MRZ, verifies checksums, opens a PACE/BAC/CAN session, and retrieves the chip data. Authenticated documents are automatically linked to the employee and project.

How are working hours calculated?

WorkingHoursSummary processes all registrations in seconds and compares them to country-specific limits. If a limit is exceeded, a clock-out action can be automatically generated.

How does synchronization between app and backend work?

Clock events, documents, and ID scans are stored locally and synchronized as soon as a connection is established. Dashboards and terminals are updated in real time via SignalR.

Can I use biometrics (such as finger scans or facial recognition) for time registration or access control on the construction site?

That depends greatly on the region in which your company operates. The explanation below is based on European privacy legislation (GDPR) and applies to organizations within the EU and the European Economic Area (EEA).


Biometric data, such as finger scans, facial recognition, or palm recognition, belong to a "special category of personal data." These may only be processed when an explicit legal exception applies. For time registration, attendance registration, or access control on construction sites, this is not permitted in most member states. In the Netherlands, this is even almost completely prohibited, unless there is a legal obligation or a serious security risk that cannot be resolved in any other way.

What we do as PA
We do not offer biometric solutions for access, time registration, or attendance control. During the coronavirus pandemic, some companies in the market temporarily used facial recognition for hygiene reasons, but this was an exceptional situation and is currently no longer permitted under the GDPR.

Our systems therefore only work with privacy-secure alternatives within Europe, such as:
  • NFC / RFID tags
  • QR codes
  • Personal accounts with verification
This allows you to fully comply with legal requirements without having to process biometric data.

πŸ‡ΊπŸ‡Έ Outside the EU/EEA (e.g., United States)
Different rules apply outside Europe. In the US, there is no federal law comparable to the GDPR. Some states, such as Illinois with the BIPA, have stricter rules and require written consent and a clear biometrics policy. Other states allow biometrics under certain conditions.

🌍 International disclaimer
For customers outside the EU/EEA, local laws and regulations apply. Biometric use may be permitted there under certain conditions. Always consult a local lawyer to determine what is permitted within your jurisdiction.
