Information for a payment account of a user of a transit system may be received. A risk analysis may be performed using the information for the payment account based on one or more parameters to determine a risk score for the user. The risk score for the user may be provided to a transit payment system. Whether the user is a high risk based on the risk score may be determined. If the user is a high risk, payment or payment authorization from the user via the transit payment system may be required before the user exits the transit system.
