British bank unveils 'digital human' bank teller

A subsidiary of British banking giant Royal Bank of Scotland (RBS) is running a pilot program using an artificial intelligence (AI) powered "digital human" to help customers with basic banking questions. The lifelike, virtual bank teller named "Cora" can answer up to 200 banking queries for NatWest customers in two-way conversations on a computer screen, tablet or mobile phone. The bank has been using Cora since 2017 and she's had about 100,000 conversations a month, the bank said on Wednesday. "Cora, the digital human is able to answer basic verbal questions like'How do I login to online banking?' 'How do I apply for a mortgage?' and'What do I do if I lose my card?'" said NatWest in a news release. Cora's human-like appearance includes ear piercings and facial expressions.
