Argentina's privacy regulator the Agency for Access to Public Information (AAIP) opened an investigation into Worldcoin's data collection practices. 

The investigation will 'thoroughly analyse' the processes and practices related to data collection, storage and usage, and address identified problems, according to the AAIP. 

Worldcoin's activitiess in Argentina had caused 'public notoriety due to the procedure of scanning the face and iris of numerous people in exchange for economic compensation in different parts of the Autonomous City of Buenos Aires and the provinces of Buenos Aires, Córdoba, Mendoza and Black river,' the AAIP said.

The move is emblematic of a broader global trend where nations are becoming more vigilant about the the data collection and user privacy of Worldcoin and other projects.
