Dispensed from a machine at the moment of arrival, the ticket is stamped with a time it does not know the meaning of yet. It travels in a cupholder, a visor, a jacket pocket, gathering the faint sweat of concrete stairwells. Its ink is thermal and impatient, fading within days as if trying to erase the whole transaction from memory.
At the exit gate it is fed back into a slot with the solemnity of a confession. The machine reads it, calculates, and the barrier lifts, or does not, prompting the low hum of a driver's dawning panic. Few objects carry so much anxiety for something worth four cents to produce. Its lifespan rarely exceeds two hours, but within that window it is, briefly, the most important document a person owns.
