Tamilnad Mercantile Bank (TMB), one of India’s trusted private sector banks, has entered into a strategic partnership with TechFini, a UPI infrastructure and fintech solutions provider, to strengthen its UPI acquiring and issuing capabilities. Under this partnership, TechFini will serve as a Technology Service Provider (TSP) to TMB.
The collaboration is aimed at enabling faster, secure, and highly scalable UPI infrastructure for payment aggregators, NBFCs, merchants, and fintech partners across India. Through this partnership, TMB will support large enterprises and regulated entities in building and scaling high-volume digital payment and collection solutions, backed by a bank-anchored UPI framework.
Beyond merchant payments, the partnership expands UPI use cases in lending and collections. Leveraging TechFini’s UPI Autopay solution, NBFCs and digital lenders integrated with TMB can automate EMI and loan repayments directly from customers’ UPI handles using e-mandates. This reduces reliance on cash and legacy collection mechanisms while improving predictability and efficiency.
TechFini’s cloud-native UPI platform covers TPAP, UPI Plugin SDK, acquiring and issuing infrastructure, and UPI Autopay. The platform is designed to process up to 10,000 transactions per second, ensuring enterprise-grade scalability, resilience, and readiness for future UPI innovations.
Together, TMB and TechFini are building a bank-anchored, full-stack UPI infrastructure that combines the trust of a regulated banking institution with cloud-native scalability, end-to-end control, and advanced security—enabling seamless payments and credit collections for merchants, lenders, and fintechs nationwide.
