I have a personal OV chipkaart since two years ago with a monthly subscription for NS (Dal Vrij) and a monthly subscription for GVB ( Randstad noord 2 stars).
since few days ago my OV is not working with GVB anymore. I can check in and check out on the train but not in the metro, bus or tram even when both subscriptions still activated.
They told me that i can not use GVB and NS in the same OV chipkaart anymore and that I need to have two separate OV for each company. Is that true? As is not comfortable to have two different ones when you are traveling every day.
thank you in advance.
hope to read your answer as soon as possible!
