Bankwest on Thursday launched \u2018Halo\u2019, a ring that enables users to make \u2018tap and go\u2019 payments as an alternative to cash or a contactless card.\nThe $39 wearable device \u2013 secured by Mastercard TM \u2013 is waterproof up to 50 metres and does not require charging or an associated mobile phone app, the bank said.\nThe ring links to a customer's transaction account and works like a contactless payment card. It is the result of a trial completed last year.\nBankwest said the device has been made possible through the organisation\u2019s agile approach to working. Staff with skills in design thinking, software engineering, product development and marketing have worked with a multi-disciplinary team to bring the product to market.\nTeam practices included daily stand-up meetings which involved representatives from key areas such as legal, compliance and architecture providing feedback to ensure Bankwest maintained a robust approach to risk management during the initiative, the bank said.\nBankwest executive general manager, technology and transformation, Andy Weir, said in a statement that the bank\u2019s new ways of working were crucial in bringing the ring to market much faster than traditional \u2018waterfall\u2019 delivery models.\n\u201cBankwest is leveraging both new technologies and new ways of working, to meet rapidly changing customer needs and we\u2019re transforming into an environment with the very best technology, design and creative professionals, who think and act differently,\u201d he said.\n\u201cThe team used a mixture of lean, agile and design-thinking, within an iterative test and learn approach. It\u2019s been hugely energising and satisfying to see the new ways of working in action, which provide a great test case for our customer-obsessed approach,\u201d he said.\nIn 2017, Bankwest recruited a team of experienced agile and \u2018customer outcome-oriented\u2019 software engineers from a local technology company.\n \nBankwest\u2019s engineering manager and team member Michael Roberts, said agile principles have been carried straight through from the tech firm to Bankwest.\n\u201cWe\u2019ve adopted an iterative approach with our key business stakeholders which has given us the autonomy to make decisions quickly. The next phase will be exciting as we gradually expand new ways of working across Bankwest.\u201d\nThe ring can be ordered through the Bankwest website, app, or in store.
