In the high, dry plains of San Luis Potosí, where the dust of the Camino Real de la Tierra Adentro still clings to the asphalt, a quiet revolution is taking place. It doesn’t involve revolutions or cartels. It involves paper. Or rather, the lack of it.

Traditionally, getting a factura (tax receipt) for a tank of gas in Mexico was a test of patience. You filled up, ran inside, waited in a line that smelled of chorizo and antifreeze, and handed over your RFC (Registro Federal de Contribuyentes). The cashier would squint at a faded laminated card, type slowly on a keyboard from 1998, and eventually— eventually —a thermal roll would spit out your proof of purchase. If you made a typo, the receipt was worthless to the taxman.
