Account-Based Architecture Makes the Medium Interchangeable
Moving fare calculation from the card to a back office means the thing a passenger presents only has to identify an account, which any contactless token can do. That collapses the distinction between a bank card, a phone, a wearable and a legacy transit card, and removes the technical basis for the media business entirely. Account-based back office platforms grow at 14.8% as a direct result. It also changes procurement, since agencies now buy a fare engine and a settlement capability rather than a card scheme, and those are evaluated by finance rather than by engineering.
