That figure is up by 60% on the 2017 figure of US$9.2 trillion, with the details contained in Juniper Research's "Digital Commerce: Key Trends, Sectors & Forecasts 2018-2022", which, as always, is on sale to relevant parties at relevant prices.
The study "found that the largest global contributor to payments was currently QR code-based offline purchases for physical goods, which now account for one-third of all Chinese instore payments by value".
"However, according to the research, although QR codes will have further growth in the Indian subcontinent and Africa, their value will be eclipsed worldwide by online purchases by 2022.
"Furthermore, it highlighted moves by traditional ‘bricks and mortar’ retailers to develop omnichannel strategies as they seek to shore up revenues by using mobile apps both for online purchases and to drive instore footfall."
Social payments drive money transfer volumes
Meanwhile, Juniper says its study "found that money transfer would be a key growth area, bolstered by rapid expansion and adoption of social payments".
"It highlighted the activities of companies such as PayPal (via its Venmo and Xoom subsidiaries) and Facebook in the space; arguing that these players were in pole position to capitalise on the increasing transition to digital of P2P payments."
What about the impact of blockchain?
Well, here the report claimed that "players across the ecosystem were poised to benefit from implementing blockchain technology for financial settlement".
"It argued that blockchain would enable increased standardisation for payment processing; substantially reduce the risk of error (including double spend) and indeed the time taken for error checking; resulting in faster, more secure and less costly processes.
"This, in turn, would allow money transfer companies to become more competitive, reduce fees to end users and thereby experience high usage volumes."
As per usual, there is a complimentary whitepaper to tempt you into purchasing the full research, dubbed "What are the Key Growth Areas in Digital Commerce?".
