Checkinandoutatwork.be by Multi-Track — the Check in at Work app for construction and cleaning
Checkinandoutatwork.be by Multi-Track is commercial software from MBSS NV for statutory attendance registration in Belgium. It supports your registration process and follow-up of NSSO responses. Checkinandoutatwork.be is an independent solution alongside the NSSO’s official online services.
This is how the app works

Clear registrations: every check-in and check-out per day and per location.
- 01
Check in and out with one tap
At the start of the activity the employee checks in via the app, and checks out the same way at the end — always with one tap, in their own language. A geofence confirms each time that they are at the declared work location.
- 02
Declaration within the deadline
Both the check-in and check-out are automatically sent to the NSSO within the legal deadline, signed with your own company's NSSO certificate.
- 03
Followed up until the answer
Every declaration — both check-in and check-out — is tracked until it is definitively accepted or rejected. You can read the outcome in plain language.
Built for the work floor
One tap to check in or out, in their own language: 12 languages, including right-to-left scripts such as Arabic.
Log in with a PIN code, workable with gloves and outdoors.
Geofencing confirms the work location; outside the zone the registration is refused with an explanation.
No tracking: the location is only read at the moment of checking in or out.
Subcontractors and temporary workers register via the same app.
Without their own smartphone
Register with a personal badge with both NFC and a QR code.
Not every worker wants or is able to use their own smartphone. With one personal Multi-Track badge containing both NFC and a QR code, they still register their own presence.
Three ways to register
- Smartphone app
- Read the badge via NFC
- Scan the QR code on the same badge
Via NFC or QR code on a central device or on the team leader's or site manager's smartphone, with NFC or a camera.
Arrival, departure and rest breaks can be registered with the badge.
The badge is personalised and produced by Multi-Track.
NSSO-compliant according to the conformity check carried out.

One device, individual records
The smartphone app can also serve as a shared registration device. Each worker presents their own personal badge with both NFC and a QR code; the record remains linked to that worker. NFC requires a compatible device; QR codes are scanned with the camera. Internal working hours and breaks can be recorded this way too.
For managers: the web portal
Alongside the app there is a web portal for those who manage the overview and compliance, with their own login.
Overview of all registrations per client, location and employee.
Planning and work schedules per team and per person.
Reports and notifications for forgotten registrations.
Full audit trail of every registration.
Roles and rights per manager, also across several legal entities.
Frequently asked questions
- Does the app work in construction as well as cleaning?
- Yes. It is the same app; in construction you register the arrival today, in cleaning both arrival and departure.
- Does the app track my employees?
- No. The location is only read at the moment of checking in or out. There is no background tracking.
- Can subcontractors and temporary workers use the app?
- Yes. They register in the same way, and you see their presences in your overview.
- We already have a time clock or badge system. Can it stay?
- Yes. Registrations that reach the NSSO via such a system are followed up on the same contracts.

In a short session we walk through the three steps of the process: checking in and out with one tap in the app, the declaration within the deadline and the follow-up until the response. We then show the portal for managers: planning, registrations per team, reports and audit trail. For cleaning, construction or both — you choose where we put the emphasis.
