Many transit agencies offer prepaid fare media, such as a season pass, stored value card, or ticket. If a driver is required to inspect passes, boarding can be longer than with payment in change. An electronic fare box with a card reader can reduce boarding time for pass holders.
Fare cards with a microchip, or smart cards, can allow transit agencies to offer a more sophisticated fare policy. Contactless smart cards need only be waved at a marked spot, and therefore can reduce payment time.<ref>Federal Transit Administration. [http://www.fta.dot.gov/12351_4362.html
