context_page_description: The Société de transport de Montréal is a public transport agency that operates transit bus and rapid transit services in Montreal, Quebec, Canada. Established in 1861 as the "Montreal City Passenger Railway Company", it has grown to comprise four subway lines with a total of 68 stations, as well as over 186 bus routes and 23 night routes. The STM was created in 2002 to replace the Société de transport de la communauté urbaine de Montréal. The STM operates the most heavily used urban mass transit system in Canada, and one of the most heavily used rapid transit systems in North America. As of 2011, the average daily ridership is 2,524,500 passengers: 1,403,700 by bus, 1,111,700 by rapid transit and 9,200 by paratransit service.
context_section_description: On April 21, 2008, the STM unveiled the contactless smart card called OPUS (a word that phonetically includes the French word puce, which is the generic French word for the chip used in any type smart card ) as a means of fare payment. In preparation for this new step in Montreal's public transportation network, turnstiles which incorporate the reader and automated vending machines had already been installed in Metro stations; buses had previously been fitted with new fare boxes that incorporate the card reader, in order to ensure the uniformity of methods of payment across Montreal's transit network and that of its suburbs.
  Costs to the STM related to the project were approximately $138 million, compared to the original estimated cost of some $100 million. The project was originally supposed to be implemented in 2006. In 2019, the STM announced plans to introduce improved OPUS card readers on buses beginning in 2020 in order to enable all-door boarding and debit card payment.
