Can applepay technology be used to pay for metro rail and fares?

In Los Angeles county, we have a tap card system where you hold it against the surface on a reader and it deducts the card value from the card. Can iphone smartphones with applepay be used as a proxy to these tap cards? Are the technologies compatible?

Edit:

According to Wikipedia, the tap cards are based on rfid: http://ift.tt/1KoSo0j

Apple pay is also based on rfid
