After completing your booking, you receive a confirmation by email. In the email you will find two links in the shape of a button:
The first button reads 'Tickets in app'. If you click on it, your ticket will be imported into the NS International app on your smartphone or tablet. The digital ticket in the app contains a square barcode that you use to open the gates on Dutch railway stations. During ticket control train personnel scans this barcode.
Be sure to have the NS International app installed on your smartphone or tablet before you import your ticket.
It is vital that you open the email with the booking confirmation on the same device that the app is installed on. If you open the email on a different device than the one that contains the NS International app, your ticket cannot be imported into the app.
The second button reads 'Print Tickets'. If you click on it, a PDF file containing your ticket opens. Print out this PDF file on A4 sized paper, and you have the tickets you need. The tickets contain a square barcode that you use to open the gates on Dutch railway stations. During ticket control train personnel scans this barcode.
Please note: When you make changes to a booking and some of the original tickets remain unchanged, a second 'Print tickets' button appears in the confirmation email. You will find the original, unchanged tickets when you click on the first 'Print tickets' button and the new, changed tickets when you click on the second 'Print tickets' button. When you have two 'Print tickets' buttons, you will need to print out the contents of both PDF files to have all the tickets for your journey.
