Abstract: A method and apparatus for collecting transit fares is disclosed. The method implements databases contained within a central database that receive data indicating value. Detectable objects are associated with an identifier, which is then associated with one of the databases. Each identifier stores available fare value data in a database. Detectors that read the identifiers are placed at trip starting and/or endings locations and are coupled or couplable to a local memory that stores the identifiers and associated available fare data. Data sets from the central database comprising an available fare value and its associated identifier are downloaded on to the local memories from the databases. Once a detectable object is detected, its associated identifier is read and a fare is debited from the available fare value. The databases and local memories are periodically updated with updated fare values associated with each identifier.
