I spent some time yesterday
at a cash machine, waiting for the partially sighted person in front of me to complete her transaction. She had someone to help her but it still seemed a terrible faff for her.
As it happens, iPM is looking at this very thing. If you're partially sighted or you know someone who is - there's an item that may be of interest to you. If so, please follow this link and add your comment on the iPM page.
