In NY if you buy $30 card. You can use for more then one people.
You did twice for sure.
First, your Hu*****and can't get in.(unless he jumped in)
Second, the subway casher wouldn't open the door(the door was locked in NY) to let you in if they didn't see you 刷卡.
Just tell the judge the truth(Most time those 便衣警察 would't show up, than, you win) .
Good luck.
