OPUS: It’s all in the name
OPUS was selected among 1,394 other possible names for the card after a survey with users, employees and participating transit authorities. The card’s name had to be neutral so as not to suggest any particular means of transportation between the bus, the train and the metro. It also had to be short and easy to pronounce.

Although the name itself does not suggest public transit, its graphics do make this reference since the card’s two curved lines evoke movement.
The card was designed internally by the communications work group.
•
 The name OPUS was chosen for its evocative nature and its innovation. It is a Latin word whose original meaning is “what is necessary, what is needed”.

•
 OPUS is also a universal and numbered musical reference. Each OPUS card will have its own number on the back. • OPUS is also simple and easy to reproduce on printed materials and any other promotional item.
• OPUS is easy to remember.
