How to add value to a SmarTrip card

1. Go to one of the machines market "Passes/Farecards." (See photo at right.)
2. Touch your SmarTrip card to the circular target (see photo below) and follow the prompts. If desired, press the audio button to get audio prompts.
3. Insert money, a used farecard or Metrochek worth less than $7 or an unused Metrochek or farecard of any value. Each one requires a separate transaction.
4. To pay by credit card, press B. American Express, Visa, Mastercard, Diners Club, JCB and Discover credit cards are accepted.
5. To pay by debit card, press C. The accepted debit card networks are listed on the front of the machine.
6. Press the plus (+) or minus (-) button until the amount displayed is the new value you want your SmarTrip card to have. The added value cannot be less than the trade-in value of the Metrochek or farecard. For credit card purchases, the default amount is $20.
7. Press C to confirm the amount to be added.
8. For credit and debit card purchases, you will be asked if you would like a receipt. Press B to receive a receipt, C to decline.
9. Touch the SmarTrip card to the circular target a final time. This updates the card and shows the new balance.
10. Remove the receipt from the tray, if you requested one.

Important: If authorization on your credit card is declined, contact the financial institution that issued you the card.
