Intelligent cards that enable visually impaired people to customise computers and ATMs automatically have been unveiled. The Special Needs Application Program Interface, or Snapi, puts a user’s preferences on a smart card. The cards can be used in cash dispensers, ticket machines and public access computers. Once a Snapi card is removed, the machine automatically returns to its default settings. The technology was developed by the Royal National Institute of the Blind (RNIB) in collaboration with Suffolk County Council and two companies based in the West Midlands.
