New MTR self-service machines armed with video cameras and a slew of features for passengers with ticket problems will debut on Sunday in Hong Kong Station. Two new machines, located at the entrance to the Tung Chung line, allow passengers unable to pass through turnstiles to resolve problems without seeking staff assistance. The machines can update entry and exit records and resolve problems for people who have lost their tickets or travelled farther than their ticket's designated destination. MTR Corp spokeswoman Amy Cheung Hiu-yan said the machines were easy to use for people who were not tech-savvy. If a customer is having trouble, they can press a button and a station assistant will appear on the screen to help guide the user. 'Say I don't know how to use buttons,' she said. 'I just press the assistance button and I can connect to the station control room ... and they can take me step by step through the monitor how to do it.' The machines, which are slightly larger than the present add-value machines, cost about HK$700,000 each. They will be on trial in Hong Kong Station for an indefinite period, Ms Cheung said. Customer reaction will determine whether they will be placed in all MTR stations. Stephen Hall, a Mui Wo resident passing through Hong Kong Station yesterday, said that even though he was usually wary of automated services, the addition of the video camera made the machines intriguing. Sophia Un Lap-man, 18, a Macau resident visiting Hong Kong to go shopping, said the money could go to better use. 'You could actually just hire people to do that and ... unemployment would be lower,' she said.
