Maquila Región 4 is a performative intervention in the labor landscape of marginal areas of Mexico. It is a mobile factory for the manufacture of electronic-textile artworks. This nomadic workshop travels to poor areas of Mexico offering the American minimum wage ($7.00 per hour, compared to $0.60 per hour in Mexico). People are hired to produce fully functional electronic circuits using conductive thread. The actual textile-schematic circuits produced are alarms which ring with different tones when a proximity sensor is activated. Once a piece is finished, a BiDi Code (similar to a quick-response bar code) is attached to the worker's embroidery. The BiDi is decoded by a consumer with a smart-phone, showing a web page that displays the worker's information: Name, location, date and duration of work session, salary recieved, a schematic diagram and a "self-presentation" section where the worker can include additional information about himself, stories, dedications, videos and receive donations.
