Techniques are disclosed for determining whether to grant a user access at an access control point of a transit system based on information about a user associated with a fare media from one or more information sources. These techniques can include receiving an authorization response after attempting to authorize payment from a fare media, and accessing at least one information source. This can include accessing historical information regarding prior transactions in the transit system made with the fare media. A determination can then be made whether to grant a user access at the access control point of the transit system. |
