Westpac will shortly unveil a revamped online banking system, and yesterday it revealed plans to launch a new online wealth management platform to support customers with superannuation, insurance and financial advice. The bank also intends to upgrade its Asian-based infrastructure, particularly the technology that supports payments and trade.In an address to the Trans-Tasman Business Circle in Sydney yesterday, Westpac chief information officer Clive Whincup said a "quiet revolution" was underway that had seen technology deliver more power to consumers, allowing them to pick and choose their financial products and services. He said all banks were being forced to respond to the "seismic discontinuity" that had been dealt the sector by the potent cocktail of computing, networking, mobility, digitisation and social media that was now available to customers.Westpac currently claims to have more than 3.6 million active online and mobile customers, processing around A$280 billion worth of transactions per month. It also boasts 254,000 active mobile business customers.Whincup said that the $2 billion that the bank has spent on the SIPs (Strategic Investment Priorities) initiative had upgraded the bank's technology, infrastructure and applications, providing a more robust platform for future innovation.Further upgrades are in the pipeline. Whincup said: "Over the next few years, we will also migrate our brands on to a unified platform, because that makes life easier for our customers." He did not provide an estimate of how long this might take or the cost of the undertaking.While the bank did not provide any further details about its new online banking platform, or the wealth management platform it is developing, arch-rival Commonwealth Bank has this year already delivered both a new banking website and the MyWealth online platform, which was launched in February.Whincup, however, claimed a few technology firsts for Westpac, noting that it remains the only Australian bank with a native iPad application and a Windows 8 phone banking application.
