The Paraguayan government sought to implement an automated fare collection (AFC) system for public transport services with nationwide interoperability, that is, such that a passenger could use a single fare medium on all public transport services in the country. The IADB hired GSD+ to support the Ministry of Public Works and Communications (MOPC) in achieving this goal. Per this contract and subsequent ones for the IADB and other clients, GSD+ worked with the MOPC on the design, regulation and implementation of a multi-operator AFC system. This involved developing an interoperability standard that includes institutional, commercial and technical specifications, which was made enforceable through a regulatory decree. The system is card-based. It was implemented by certified AFC service providers who issue the smart cards, run sales and top-up networks, and provide on-board validators to bus operators.


GSD+ designed and developed a transaction clearing house for the AFC system, which is currently run by the MOPC’s Vice Ministry of Transport. In addition, GSD+ serves as issuer of secure access modules (SAMs) for the system and performs certification of AFC service providers on behalf of the Vice Ministry of Transport.


Paraguay’s interoperable AFC system has been implemented on the entire fleet of 2,100 buses in Asuncion, which has a daily ridership of 620,000 in 2022. Since February 2021 all public transport payment transactions in Asuncion are electronic, given that cash payments are no longer accepted. The system is expected to be extended to other urban areas in the future.

GSD+ extended the design of Paraguay’s interoperable AFC system to support intercity transport services and updated the AFC system regulations accordingly. The AFC system is expected to be implemented on 1,800 buses used for intercity transport services throughout the country.
