The Impact of Instant Digital Transactions on Consumer Spending Behaviour

The rise of instant digital transactions via UPI, mobile wallets, and contactless payments has transformed consumer spending by enhancing convenience but also encouraging impulsive purchases and reduced savings. This study investigates the psychological and behavioural impacts of digital payment systems, applying the Theory of Planned Behaviour to analyse how Attitude, Behavioral Intention, and Perceived Behavioral Control influence purchasing frequency. Addressing gaps in existing literature that often emphasize trust and usability over behavioural consequences, the research explores how digital spending behaviours are shaped, especially across demographic segments. Using a quantitative approach with SmartPLS-based Partial Least Squares Structural Equation Modelling, data from 317 digitally active consumers was analysed. The findings show Behavioral Intention as the strongest predictor of purchase frequency, followed by Attitude, while Perceived Behavioral Control showed minimal influence. High model reliability and good fit indices reinforce the results. The study concludes that consumer intent, more than perceived control, drives digital purchases. It recommends integrating behavioural feedback tools and financial education in digital platforms to foster healthier financial habits and ensure long-term economic well-being in a cashless economy.
