Unlocking the future of paytech: exploring biometric payment card adoption patterns Liébana Cabanillas, Francisco José Irimia-Diéguez, Ana Albort Morant, Gema Zarco, Carmen Biometric payment card FinTech Paytech With the transition to a cashless society and the evolving regulatory framework gov erning electronic payments, the advent of novel payment systems has become increas ingly apparent. In this context, biometric payment cards have emerged as a promising alternative to enhance security, convenience, and efficiency in electronic transactions. An online questionnaire was administered to a sample of users experienced in mobile payment systems, and structural equation modeling was utilized to identify the vari ables significantly affecting usage and recommendation. The results confirm the pro posed hypotheses, except for those related to social influence and perceived risk. This study provides a unique contribution by investigating the factors influencing the adop tion and word‑of‑mouth (WOM) of biometric payment cards, integrating elements from the unified theory of acceptance and use of technology 2 (UTAUT2), general risk theory, and trust theory. This research is highly relevant for financial institutions, tech companies, marketers and policymakers, as it informs user strategy development for businesses operating within the biometric payment sector and suggests guidelines for enhancing consumer trust and reducing perceived risks associated with biometric payments. 2026-03-04T08:56:31Z 2026-03-04T08:56:31Z 2026-02-24 journal article Francisco Liébana-Cabanillas & Ana Irimia-Diéguez & Gema Albort-Morant & Carmen Zarco, 2026.
