Premise: The Beijing Municipal Administration & Communication Card (), more commonly known as the Yikatong (literally One-card pass), is a store-value contactless smart card used in Beijing, China, for public transportation and related uses. It is similar to Hong Kong's Octopus card, Singapore's CEPAS, or the Oyster Card used by Transport for London in London, England.
Hypothesis: Beijing Municipal Administration & Communication Card produces smart cards similar to other companies in the same field.
