The card is also available in electronic form, free of charge, in Apple Wallet, thereby bypassing the need to purchase the plastic USD $2 card. It is administered by the Los Angeles County Metropolitan Transportation Authority (Metro), and the card and fare collection systems are manufactured by Cubic Transportation Systems.
