The number of mobile wallet transactions as a proportion of total card based spending more than doubled in the period.
In December ANZ customers favoured their smartphones and wearables for 4.5 per cent of all transactions, compared with 2 per cent for the same time last year.
ANZ data show mobile wallet transactions reached 3.9 million in December, compared with 1.6 million in the same month in 2016.
Mobile wallets are still a relatively new technology, with options for consumers being rolled out progressively in Australia. Looking back over 18 months the sustained emerging growth in transaction volumes is clear as adoption builds.
