A new report from Worldpay, a provider of technology-based payment systems for merchants, banks and capital markets firms, says digital and mobile payments have become the preferred payment methods, with Buy Now, Pay Later products gaining rapid acceptance across the globe.Data from Worldpay (acquired by financial technology provider FIS in July 2019) showed that in 2019 nearly two million Aussies, or almost one in 10, used BNPL from providers such as Afterpay, Zip Pay or Humm. Phil Pomford, general manager for global ecommerce, at Worldpay Merchant Solutions, said, "With their unrivalled convenience, 'Buy Now, Pay Later' products have emerged as an attractive option for consumers seeking an alternative to traditional credit cards and have surged in popularity over the past year."In its 2020 Global Payments Report, published today, Worldpay estimates BNPL payments represented eight per cent of all e-commerce payments in Australia in 2019. This was up from three per cent in 2018, an increase in usage of more than 166 per cent.FIS has estimated that BNPL players will double the sector's market share by 2023, with over four million - or one in five - Australians tipped to use one or more of the alternative payment providers' products by 2023.Looking globally, across the 40 countries analysed in its report FIS has seen year-on-year BNPL transaction volume increase by 102 per cent, and the consequent boost in turnover touching 130 per cent.The Worldpay report also reveals that online use of digital and mobile wallets such as Apple Pay, Google Pay, and PayPal has risen sharply in popularity, with nearly one quarter (22 per cent) of Australians using one of these methods to pay for goods online in 2019, up by four percentage points over the 2018 estimates.The acceptance of these payment methods is even more pronounced at the point of sale, where digital and mobile wallet payment use has trebled from two percent of all transactions in Australia in 2018 to six per cent in 2019. However, debit and credit cards (accounting for 40 per cent and, 31 per cent, respectively) and cash (14 per cent) were still preferred by the majority of Australians lining up to make payments at physical checkouts in 2019, Worldpay reported.Rivalry among competing payment systems is set to continue, with Worldpay forecasting that Australia's e-commerce market will expand by more than 40 per cent to more than US$47 billion by 2023. Point-of-sale transactions in the country are expected to grow by over 21 per cent, to US$756 billion by 2023.The data was published as part of Worldpay's 2020 Global Payments Report, an analysis of the evolving payment landscape around the world and included POS data for just the second year. Previous global payments reports focused exclusively on e-commerce payment methods.Globally, digital and mobile wallets accounted for 42 per cent of overall transactions in 2019, rising to 58 per cent of e-commerce transactions in the Asia Pacific region. Worldpay forecasts that figure will be heading towards 70 per cent of payment transactions in APAC by 2023.
