From the Transit Card to the Opuscard

The first fare card, which was later integrated into the Liberec Region’s public transit system, was created even before IDOL. Does anyone still remember the Liberec City Card? It was introduced back in 2006.
Later, the Opuscard was introduced, along with several different variants, until we arrived at the current Opuscard+ format. Although it is now partially replaceable—for example, as an identifier for time-based passes—it remains an important part of the integrated transit system.
