Travel ticket app helps you pass public transport gates in the Netherlands without unwanted opening of your smartphones wallet while presenting a barcode of a train ticket.
In the Netherlands, the station gates have readers that simultaneously read both barcodes and the NFC chip in your smartphone. This can cause problems when trying to scan a photo or PDF of an (international) train ticket. Because the NFC chip is also scanned, your smartphones wallet opens, and the tickets barcode disappears from the screen. To prevent this, you can open the international train ticket in the Travel Ticket app. This will block the opening of your wallet and allow for a smooth passage through the gates. In the app, open the PDF document or photo of your ticket, or open the ticket itself and use the Share -> Present as ticket option.
