How do I know what ticket or how many journeys are left on my card? My card isn’t working. What should I do? How do I use a ticket on an card? How long is a travel pass or ticket on the electronic card valid? Can I scan my ticket on an card when it is still in my wallet? I bought a ticket on an card, within how much time after purchase should I use it? How can I buy a ticket on an card? What is the difference between a ticket with a magnetic strip and a chip? This card is more robust and I can’t top it up. Is that good for the environment?
