A "pass" is a card or ticket that is used repetitively to gain access to subways, trains and busses. Typically, taxis are privately owned and are not included as part of the pass plan.
I'm sure you will find different names for these passes depending on the city. In New York, it's called a Metro Card. In Boston, it's called a Charlie Card. But if you went to a clerk in any of these cities and asked for a "metro pass" or "transit pass", they would understand.
