A consortium of two of New Zealand's biggest banks, its three mobile phone companies and the country's main payments network has suspended its digital wallet service aimed at Android users.The Semble wallet was launched to customers of National Australia Bank's BNZ and Commonwealth Bank of Australia's ASB with contactless Visa and Mastercard debit and credit cards in March last year. The Paymark payments network that handles 75 per cent of New Zealand's electronic payments was also a shareholder.Semble said the service was suspended on Friday after a strategic review by its owners, which include BNZ, ASB, Spark, Vodafone and Two Degrees Mobile. The payment system used Android phones with NFC chips and could be used at more than 20,000 contactless terminals. ASB and BNZ customers had to get a special SIM card from their mobile network to make the service work.Semble chief executive Rob Ellis said Semble would refocus the business to develop new services, but the payments part of the mobile wallet had been suspended after poor take-up."Mobile payment services haven't had the speed of uptake and usage we expected due to a variety of reasons," Ellis said."These include low levels of consumer awareness of mobile payments and relatively low volumes of contactless terminals, especially outside the major retail brands, although contactless transactions in general are growing," he said.
