The Des Moines Regional Transit Authority is planning to change how it accepts fares on city buses.
DART is planning to buy new fare boxes that would allow passengers to use their smart cards.
Officials say the cards will give customers more flexibility. The changes could also mean the end of tokens.
DART plans to pay for the new devices with a $3-million federal grant.
A series of public meetings will start next week for those who want to weigh in on the changes.
