Tools for Humanity's Worldcoin is expanding its iris scanning operations across several key locations in Mexico. Recent reports indicate the addition of scanning centers in Mexico City, Monterrey, and Guadalajara, making Mexico the third-largest base for Worldcoin in Latin America, following Argentina and Chile where the operations are larger.

The safety and protection of biometric data collected by Worldcoin are under scrutiny in Mexico, with lawmakers such as María Eugenia Hernández from the Morena party calling for investigations by the INAI to assess the security of personal information and tokens obtained through Bitcoin transactions.

Operations in Spain and Portugal have been temporarily halted due to concerns related to data privacy, particularly concerning the personal information of minors. Similarly, Argentine and Chilean authorities are evaluating the implications of Worldcoin data collection, with some instances leading to the imposition of fines.
