Older persons turn directly to the branch for accessing to banking services because they feel safer and they have problems when they interact with bank interfaces. These interfaces are not adapted to older people needs and capabilities. Bank4Elder project aims to develop innovative web and Automatic Teller Machine (ATM) interfaces involving older persons along all the design and development process. The results showed high levels of satisfaction of older persons with the new interfaces, which combine age-friendly and aesthetic characteristics. Moreover, designers and developers have become aware of the older persons profiles and their real needs.
