The digital payment infrastructure of a nation defines the robustness with which it intends to address multi-dimensional issues such as financial inclusion, establishing secure gateway for payments, exploring transparent and economical channels for payments and providing fast and user-friendly interface for transactions. India has experimented with several innovative payment solutions since the last two decades. Digital payment systems play an instrumental role as an enabler contributing to the growth of the economy, however, whether they have any long run relationship with the economy is yet under explored. The present study attempts to analyze the long-run impact of digital payment systems on the Indian economy using Engle-Granger cointegration test. The transactions done through Immediate Payment Services (IMPS), National Electronic Fund Transfer (NEFT), Real Time Gross Settlement (RTGS), debit transactions through National Automated Clearing House (NACH) and Point of Sale (PoS) transactions done through Credit and Debit Cards were analyzed for establishing the long run relationship of digital payments in India with its Gross Domestic Production (GDP).
