Because I can be slow on the uptake, I thought MBTA CharlieCards were only for those with monthly passes. A friend told me otherwise, and a T worker at North Station gave me one.
I tried to register it online and got rejected. When I called the 800 number, a friendly employee explained that the online system only works with older cards. “Would you like me to send you an old one?” she asked. Sure, I said, and a few days later one arrived in the mail. I just registered online and added $20 to it without any problem. And the brand-new card sits unused.
