Global card expenditure to reach $45tn by 2023 on back of contactless payments — RBR — “RBR forecasts global card expenditure will grow at an average of 10% per year between 2017 and 2023 to reach US$45.2tn. The average value of a payment, however, will fall from $67 to $62 over the same period as the influence of contactless cards grows — the latter are typically used for the lowest-value payments, and particularly those which would previously have been made with cash.”
