When you board and scan your Tapp Pay barcode on the payment reader, it will provide two different types of messages which indicate that you need to add funds to your account:

Last Ride / Add Funds (Yellow) – means that your account is now negative and are being provided our One More Journey Feature. You need to add more funds before boarding another vehicle.

Lack of Funds – means that your account is still negative and you are not able to board until you load more funds, bringing your account back to a positive balance state.

For those utilizing Tapp Pay via phone you can check your balance through the Transit app by going to settings under the gear icon in the top corner of the app, which will track your account balance and history in real time.
