Fintech-Enabled Payment Solutions in Omnichannel Retail: Trust, Transaction Behavior and Digital Financial Interfaces

Abstract

This study examines fintech-enabled payment solutions in omnichannel retail as consumer-facing financial technologies that shape transaction behavior, trust formation, and the functioning of digital financial ecosystems. The study draws conceptually on digital payment adoption research, trust-based perspectives on fintech platforms, and the broader view of payment technologies as components of digital financial ecosystems. Rather than treating payment merely as the final operational step of a purchase, the paper conceptualizes mobile payments, digital wallets, and related solutions as financial interfaces through which consumers evaluate speed, reliability, security, and the credibility of the wider retail-financial environment. The empirical basis of the paper is a consumer survey originally designed to examine omnichannel shopping experiences, which is reinterpreted here through the lens of payment-related trust, perceived ease of use, process continuity, and perceived control. The findings show that consumers assign high importance to integrated channel operation, simplicity, transparency, and reliable information, and that coherent omnichannel environments are associated with stronger trust, greater return intention, and a higher sense of control during shopping. The study suggests that payment-related trust is embedded in consumers’ broader evaluations of whether retail processes are consistent and reliable across channels. While the empirical material provides meaningful support for the trust- and adoption-related dimensions of the framework, the relationship between specific payment forms and responsible financial behavior remains more exploratory. The article contributes by repositioning payment within omnichannel retail as a fintech-related financial interface that influences consumer trust, transaction-related behavior, and the broader logic of digitally mediated financial interaction. The paper also argues that mobile payments, digital wallets, and BNPL should be treated as distinct fintech models with different implications for trust, perceived risk, and consumer behavior.
