As long as it has a Visa, Mastercard, Discover or Amex logo on it, you can use it as a payment method when you reload using myhopcard.com, the Hop app or 1-844-MYHOPCARD, or at the TriMet and C-TRAN ticket offices (where you can also buy a Hop card). However, you can’t use a commuter benefit card or transit debit card to buy or reload a Hop card at Hop retailers such as grocery stores.
