We exploit the release of a mobile application for a financial aggregation platform to analyze how technology adoption changes consumer financial decision making. The app reduced the cost of accessing personal financial information, and we find that this led to a drop in non-sufficient fund (NSF) fees. Because of the manner in which these fees are incurred, this represents an unambiguous welfare improvement for users of the platform. The leading explanation for this result appears to be mistake avoidance due to easier access to information.
