Abstract:
We examine how an innovation in payment technology impacts on consumer payment choice and cash demand. We study the staggered introduction of contactless debit cards between 2016-2018. The timing of access to the contactless technology is quasi-random across clients, depending only on the expiry date of the existing debit card. Our analysis is based on administrative data for over 21'000 bank clients and follows a pre-analysis plan. Average treatment effects show that the receipt of a contactless card increases the use of debit cards especially for small-value payments. However, we find only a moderate average reduction in the cash share of payments and no reduction of average cash demand. Treatment effects on payment choice are strongest among consumers with an intermediate pre-treatment use of cash. Explorative analyses reveal that effects are largely driven by young consumers in urban locations.
