This book investigates how the invention and evolution of the Automated Teller Machine (ATM) served as the primary catalyst for the transition to digital banking systems. Bernardo Batiz-Lazo, a professor of business history, utilizes extensive archival research and industrial organization theory to argue that the ATM was not merely a convenience tool, but a fundamental driver of structural change in retail banking. The work examines the complex interplay between technological innovation, regulatory frameworks, and the shifting labor requirements of financial institutions from the 1960s to the present.

Experts in economic history identify this work as a comprehensive study of the institutional shifts within the retail banking sector. Readers frequently note the academic density of the prose, which provides a rigorous look at the intersection of technology and financial regulation.
