A white paper from Juniper Research projects mobile wallet transactions to increase to $1.35 trillion globally in 2017, an annual increase of 32%; the data shows that the Far East and China are currently accounting for most of the market transactions with growth specifically from Alipay and WeChat; PayPal and Apple are also noted as leading market providers; in the European market the Payment Services Directive 2 (PSD2) is also expected to be a factor supporting near-term growth in mobile wallet transactions.
