India is expected to double retail digital payments to USD 7 trillion by 2030, according to a study by Kearney and Amazon Pay. The report, ‘How Urban India Pays’, suggests that affluent consumers lead the way with the highest Degree of Digital Payment Usage (DDPU), using various modes of digital payment for 80% of their transactions. The study was based on an online survey of over 6,000 consumers and over 1,000 merchants across 120 cities.
