Prosa
“Can Prosa modernize Mexico's core interbank payment infrastructure to remain the dominant switch and acquirer as digital payments and open banking reshape the Latin American market?”
Founded in 1968, Prosa (Promoción y Operación S.A. de C.V.) has operated for over five decades as Mexico's largest electronic payments network and one of the largest payment processors in the Americas. The company serves as the critical interbank switch connecting Mexican banks, ATMs, and card networks, and is recognized by global payment schemes like Adyen as an acquirer for Mexican card transactions. In 2025, Prosa partnered with ACI Worldwide to undertake a major infrastructure modernization, signaling a strategic push to remain competitive in a rapidly evolving Latin American payments landscape. The company operates as an acquired/merged operating subsidiary, backed corporately.
