Downloading products to your OV-chipkaart
If you wish to take advantage of NS products such as class changes, Keuzedagen or combined travel discounts, simply download them onto your OV-chipkaart and activate them.
Changing class
When you order a season ticket or an OV-chipkaart, it is usually for 1st or 2nd class. But you can also choose to change the class temporarily or permanently.
Keuzedagen
Travelling with Keuzedagen (Optional Days)? Before you can use your Keuzedag, you must download it to your OV-chipkaart at an NS Ticket Machine.
Combined Travel Discount
If you wish to travel with someone who has an NS season ticket (with the exception of Kids Vrij (Kids Free)) or a student travel product, then you need a co-travel code to receive a 40% discount during off-peak hours. The NS season ticket holder may take up to 3 people along at a 40% discount during off-peak hours.
