Thank Lily and Mrkirkland for answering my question.
But I do not understand what it exactly means that “if the travel cards end in CA”, is it a special card with the letter “CA” at the code end? Do I have to specify when I purchase it?
Also, a related question: if two person travel together, do we need to buy two cards, one for each person, or we can just have one card and use it to but two tickets whenever we take the bus or train?
Thanks a lot.
@1stvist SuiCA and IcoCA - they have “ca” at the end. If you want to use it for contactless entry to the subway etc. then you need one card for each person. You can have one card between you, but you will then need to use the card to purchase paper tickets - which negates the usefulness of having a contactless travel card.
