In and around the station

Information about how we use your data to enhance security and improve our services at and around the station.


What personal data do we use?

For greater safety and security in and around the station and to improve our services, we use counter sensors that count how many people pass by them and analyse local traffic flows. The footage shot by these sensors is not saved on the sensor or in any other way whatsoever. In the past, NS also used WiFi tracking, but we stopped doing so as of 7 January 2021. 

What do we use your personal data for?

Every day, more than 1.2 million travellers use the train stations in the Netherlands. As hubs of pedestrian traffic and public transport, a station is a special location that lets you transfer between trains, urban and regional public transport, bikes, cars, and increasingly diverse services and facilities.

The basis for data processing is: legitimate interest.

NS is constantly working to enhance security and improve its services in and around the station. To that end, it is essential to gain insight into the flows, walking routes, waiting times, and waiting areas for travellers and other station users. In this context, we are currently mapping traveller flows at a number of large stations by means of sensors that detect WiFi signals emitted by mobile devices, which is also known as WiFi tracking. We use this method in combination with counter sensors in such a way that no data can be attributed to individuals, whether directly or indirectly. Your privacy is therefore guaranteed.

We use the resulting non-attributable data for social purposes, such as security and crowd control at and around the station, as well as for commercial purposes, such as choosing the locations for specific services and shops at the stations.

Stations where WiFi sensors are used can be recognised by a pictogram indicating their presence. NS uses counter sensors at the stations Amsterdam Centraal, Amsterdam Zuid, Amsterdam Bijlmer Arena, Utrecht Centraal, Schiphol Airport, and 's Hertogenbosch.

With whom do we share this data?

We contract third parties to provide IT and marketing services. These third parties process our information solely for our own internal use, and for no other purpose. We have made agreements with these parties pertaining to the processing of personal information.

We may transfer your personal information to parties outside the European Economic Area under certain circumstances. In that event, we will take suitable measures with these parties, for example by agreeing to the standard contractual clauses adopted by the European Commission.

How long do we store your data?

The footage shot by the counter sensors is not saved on the sensors or in any other way.

Use of drone video images during Zandvoort Grand Prix 3-5 September 2021

After the race, NS will use a drone to carry out a trial counting the flow of passengers towards the station by means of automatic processing of video images. NS is conducting this test to improve its safety operations in and around the station ('crowd control'); in the interests of your safety and ours. We are collecting and processing the images for the purpose of counting and validating the drone count data. We do not intend to show people recognisably in the images, but it is unavoidable that some people may be recognisable. The camera images will be destroyed following the test.

What personal data do we use?

During the Grand Prix in Zandvoort, video images will be made at predetermined moments with a drone, either by an NS employee or a drone pilot hired by NS.

What do we use your personal data for?

NS is continuously working to increase safety and improve the service we provide at and around the station. For this purpose, it is essential to have insight into the walking flows, routes, time spent by passengers and other station users and their chosen waiting areas. This is particularly important during large-scale events such as the Grand Prix in Zandvoort. For this reason, after the Grand Prix, we will be surveying the flow of visitors to and from the station. We will ensure that the images are processed safely and carefully. Your privacy is therefore guaranteed.

The basis for the processing is: legitimate interest.

With whom do we share data?

We engage third parties to perform IT services. These third parties are processors for us and process the data only for our benefit and for no other purpose. We have made agreements with these parties regarding the processing of personal data.

We may transfer your personal data outside the European Economic Area in certain circumstances. If we do so, we will take appropriate measures with these parties, for example, by adhering to the standard clauses set out by the European Commission.

How long do we keep your data?

We will not keep the video images of the drone longer than strictly necessary. We will keep the video images for a maximum of three months.
