Ensenada’s municipal government has replaced the traditional paper health card, known as the tarjeta sanitaria, with a digital QR code system to verify the health status of registered sex workers in the city.
Arturo Manríquez Ayub, head of Municipal Medical Services, explained that sex workers operating in nightclubs and massage establishments must undergo two STI screenings per month. The new QR code now serves as their official proof of health authorization, replacing the physical card that had been in use for years.
How the New System Works
Under the updated system, establishment owners and inspectors can scan a worker’s QR code to instantly confirm whether she has completed the required health exams. The paper tarjeta sanitaria was long the standard tool for this verification, but officials say the digital format is harder to forge and easier to check during inspections.
Municipal authorities reported good cooperation from nightclub owners in adopting the new system. The QR codes apply specifically to workers in registered establishments, including nightclubs and massage parlors that fall under the city’s regulatory framework.
Limits of the System
Officials acknowledged a significant gap in coverage. The QR code program only reaches workers in licensed, registered venues. Sex workers who operate independently through social media platforms or online classified ads remain outside municipal health oversight entirely. Authorities did not announce plans to address this gap.
Ensenada’s health card system has been in place for decades. Workers subject to the program face fines, arrest, or other penalties if they cannot produce valid proof of their health screenings during surprise inspections, which typically occur once or twice a month. The shift to QR codes modernizes this enforcement mechanism without changing the underlying requirements.
The move mirrors similar efforts internationally to digitize health verification for sex workers. In 2024, the city of Bacolod in the Philippines proposed adding QR codes to the “pink cards” issued to commercial sex workers for similar public health tracking purposes.
Ensenada, located about 80 miles south of the U.S. border, draws significant nightlife tourism from both cruise ship passengers and Southern California visitors. The city’s regulatory approach treats sex work as a public health matter managed through its Municipal Medical Services office rather than through criminal enforcement alone.
