password-entering assistant for the blind / fo blind to pay by phone

password-entering assistant for the blind
password-entering assistant for the blind

It has been a difficulty for the blind to enter the password accurately by themselves. First, unlike the old-fashioned cellphone which has buttons for the blind to touch and distinguish, the new one is only equipped with a flat-screen. Asking for help is not considered a good solution, either, as it may be a threat to the security of their account. So they have to do it by themselves and most of the time they may experience failure several times before entering the correct password. This experience makes them feel anxious and awkward especially when there is a long check-out line waiting.
