An inkloksysteem (clock-in system) records when your employees start and stop work, so you can calculate hours, breaks and overtime. In the Netherlands, no specific tijdklok (time clock) is mandatory. The Arbeidstijdenwet (Dutch Working Hours Act) does require a proper record of working and rest times, kept for at least 52 weeks. For field teams on sites and in vans, a wall terminal at the office rarely works. A smartphone app, a badge at a site terminal or registration through the vehicle fits better. With a works council, you need its consent first.
Suivo’s time tracking software for field teams in the Netherlands supports all four methods: app, badge, fixed on-site terminal and vehicle.
What is an inkloksysteem, and what does “inklokken” mean today?
“Inklokken” comes from the old punch clock: an employee pushed a card into a tijdklok, which printed the time. “Uitklokken” was the same at the end of the day. The word stayed, the technology changed. A modern inkloksysteem has two parts:
- A way to register the moment: an app, a badge or key tag (druppel) at a terminal, a unit in the vehicle, or a shared tablet.
- Software that turns moments into hours: it applies breaks, flags missing clock-outs, lets a supervisor approve, and sends the result to payroll.
For a construction company or an installer, the difficult part is the first one. Your people start at a site, a customer’s home or the yard, not at a reception desk. For a broader overview of system types, read what a time tracking system is.
This article is the Dutch twin of our Belgian guide on choosing a prikklok, badge or app in Belgium. The rules below apply to the Netherlands only.
Is clocking in mandatory in the Netherlands?
The law does not require a tijdklok, an app or any specific device. What it requires:
- A proper record. Under article 4:3 of the Arbeidstijdenwet, the employer keeps a “deugdelijke registratie” (proper record) of working and rest times that allows supervision of compliance.
- 52 weeks. Under the Arbeidstijdenbesluit (Working Hours Decree), you keep these records for at least 52 weeks from the date they relate to. For drivers of goods vehicles, the transport rules apply instead, with 104 weeks.
- Limits you must be able to show. Adults may work at most 12 hours per shift and 60 hours per week, and on average 48 hours per week over any 16 weeks. They get at least 11 hours of daily rest, which may be shortened to 8 hours once per 7 days when the work requires it.
Enforcement is done by the Nederlandse Arbeidsinspectie (Netherlands Labour Authority). According to its fine list, the base fine for a missing working and rest time record is EUR 10,000, and a breach of working or rest time rules costs EUR 200 per person per day. These base amounts apply to employers with 50 to 99 employees. They are multiplied by 0.5 below 10 employees, 0.75 for 10 to 49, and 1.5 from 100 employees.
One exception: the registration duty does not apply to adults earning at least three times the statutory minimum wage, unless they usually work night shifts, do work with serious safety or health risks, or work on or from a mining installation or wind farm. For most site workers, it applies. Our guide to the Dutch Working Hours Act for employers covers all limits.
So a clock is not mandatory, but a reliable record is. For a mobile team, a digital inkloksysteem is the easiest way to prove it.
App, terminal, badge or vehicle: which method fits?
| Method | How it works | Best fit | Watch out for |
|---|---|---|---|
| Smartphone app | Employee clocks in on their own phone, often with location at that moment | Crews that move between sites, service technicians | Phones left in the van, clocking in on the way |
| Fixed terminal (tijdklok) with badge or tag | Employee holds a badge or druppel against a reader | Yard, workshop, large sites with one entrance | Queues at start time, one device per location |
| Vehicle registration | Employee identifies in the vehicle with an RFID tag, button or card | Drivers, installers who start from the van | Passengers and people who do not drive |
| Shared tablet (kiosk) | Several employees clock in on one device with a PIN | Site cabins, depots | Colleagues clocking in for each other |
| Biometric terminal | Fingerprint or face scan | Rarely allowed for this purpose | See the privacy section below |
| Paper or Excel | Hours written down afterwards | Very small teams with fixed hours | Hours from memory, retyping, no audit trail |
Many field businesses combine methods: drivers register through the vehicle, site crews through the app, and yard staff at a terminal. Suivo describes exactly that mix. Teams can register via the mobile app on their own smartphone, by scanning a badge, at a fixed on-site terminal, or automatically through the vehicle they drive. Vehicle clock-in uses RFID, buttons or cards. All methods feed the same validation dashboard. If you still work in spreadsheets, see when urenregistratie in Excel stops working.
Privacy: what do the AP and the works council expect?
An inkloksysteem processes personal data, so the AVG (the Dutch name for the GDPR) applies. The Autoriteit Persoonsgegevens (AP, the Dutch Data Protection Authority) sets out what that means for employers.
Works council consent. According to the AP, a personnel monitoring system (personeelsvolgsysteem) includes a system that registers attendance, time and access, a badge system, and a GPS tracker or on-board computer in a vehicle. Under article 27 of the Wet op de ondernemingsraden (Works Councils Act), the works council must consent before you introduce it. This also applies when the system could monitor staff but you do not plan to use it that way. If the works council refuses, you can ask the subdistrict court (kantonrechter) for permission. A works council is mandatory from 50 employees.
General conditions. The AP’s conditions for monitoring employees are:
- a legal basis, usually legitimate interest. Consent works poorly because employees can hardly refuse;
- necessity: no less intrusive way to reach the same goal;
- informing staff about what you check, why, when and how;
- a DPIA (data protection impact assessment) before systematic monitoring, such as GPS trackers in vehicles.
Vehicles. The AP describes letting drivers switch the tracker off during private trips as common practice.
Biometrics. The AP says biometric access control, such as a fingerprint, is almost always prohibited. Employee consent will rarely work, because employees depend on their employer. For time registration, choose a badge, tag, PIN or app.
Practical tip: an app that only reads location at the moment of clocking in is easier to justify than continuous tracking. Write down what you record and why, before you talk to the works council.
From clock-in to payroll: how do you avoid manual corrections?
The clock is the easy part. The cost is in what happens after: missing clock-outs, hours on the wrong project, surcharges added by hand, and a payroll run that waits for corrections. A good flow looks like this:
1. Registration at the place where work starts (app, badge, terminal or vehicle).
2. Automatic checks: missing clock-out, shift longer than planned, break not taken.
3. Approval by the supervisor, ideally the same week.
4. Export of approved hours, absences and surcharges to payroll.
Suivo brings hours, absences, mobility fees and surcharges into one validation dashboard, with a complete digital trace of every hour ready for export in one click. Approved hours sync with planning, ERP and payroll systems through an open API. Tell us which Dutch payroll or HR platform you use, and we will check how the connection works for you. For drivers, Suivo also shows remaining driving time from tachograph data, and our scheduling tool plans driver routes and orders. Read more about why automating time registration pays off.
How do you choose an inkloksysteem in 5 questions?
1. Where does the working day start? At the office, on a site, at a customer or in the van? Choose the method that works at that place.
2. Who drives and who does not? Vehicle registration suits drivers. Passengers and site crews need an app or badge.
3. Do you have a works council? Then plan its consent, your DPIA and your staff information before you buy.
4. Which cao applies? Your collective agreement may change breaks, the 4-week limit and roster notice. Check that the system can apply those rules.
5. How do hours reach payroll? Ask for a demo of the full flow, from clock-in to approved export, not only the app.
Be honest about scale too. A team of five with fixed hours at one location may not need more than a simple terminal or a well-kept spreadsheet.
Frequently asked questions
What is an inkloksysteem and how does it work?
An inkloksysteem is a system that records when an employee starts and stops work. The employee clocks in with an app, a badge, a tag or a vehicle unit, and the software turns those moments into worked hours, breaks and overtime for approval and payroll.
What does inklokken mean?
Inklokken means registering the start of your working time, originally by punching a card in a tijdklok (time clock). Uitklokken is registering the end. Today most people clock in digitally, with a badge, a phone or through their vehicle.
Is clocking in mandatory in the Netherlands?
No specific clocking method is mandatory. The Arbeidstijdenwet does require employers to keep a proper record of working and rest times and to keep it for at least 52 weeks. The Nederlandse Arbeidsinspectie uses a base fine of EUR 10,000 when that record is missing.
What is the best hours registration system?
The best system is the one your people actually use at the place where they work. For office staff, a badge at the door can be enough. For crews on sites and in vans, look for an app or vehicle registration, approval by a supervisor, and a clean export to payroll.
Can I use a fingerprint time clock?
In practice, almost never. The Dutch Data Protection Authority (AP) says biometric access control is almost always prohibited, and that employee consent is rarely valid because employees are not in a position to refuse. Use a badge, tag, PIN or app instead.
