There is an access problem for many blind and deaf-blind users of ATMs, online banking and the Web. This paper looks at a proposed potential solution for those users who, though classified as legally blind can still recognise on screen patterns representing textual characters, words or symbols. Such a system, the Dynamic Pattern System (DPS), has been developed to enable the matching of such patterns to a visually disabled person's remaining vision system. This paper also considers some of the security problems posed by the blind and the deaf-blind undertaking routine banking operations and use of the DPS as a potential aid.
