Check In & Check Out With OV-Chip Card

Check in and check out has been introduced with the OV-Chip card. This means that I always have to check out or check in with my OV chip card at the beginning and end of the journey. If it doesn't work or goes wrong, I can go to the counter of the NS or the bus operator at the major stations. At the smaller stations or if the machine in the bus or tram doesn't not work, I can go to the website 'uitchecken gemist'. After filling in the form on the website to request my money back, I can also leave my email, so that I will be notified every time something goes wrong during check in or check out.

Why Is The Data On The OV-Chip Card Big Data?

I was suprised last year by the NS with an advise what kind of card I could buy to profit from traveling with the NS. The advice was based on my travel record of the years before. This is a way my travel data with the OV can be used. There are also other benefits of using the collected data of the OV-Chip cards like which tracks are the most busy ones and when. By nowing this they can plan the trains and buses better.
