Signature Area (3 of 4)

Issue: Users may have difficulty determining the boundaries of the signature area.

The signature screen on a kiosk card reader is shown.  A box containing an X and the signature line fills about a third of the screen.  Users must sign within the box, but the box is not tactilely discernible.

On some kiosks, the signature area is a subset of the full signature area screen, and the boundary of the allowable area is represented graphically and is not tactilely discernible. If a user's signature is not fully within the signature area, it may not be accepted by the machine. Users with visual impairments may be unable to see the boundary of the allowable area, and may therefore be unable to determine if they are signing within the boundary.

Populations Impacted: Users who are blind; users with low vision.

Potential Solutions:
  • Allow users to sign anywhere on the screen. The boundary of the screen should be tactilely discernible, so if the allowable area for signatures fills the entire screen, users can use the edges of the screen to determine tactilely where they should sign.

  • The signature screen on a kiosk card reader is shown.  An X and the signature line fill the width of the screen, and users are allowed to sign anywhere on the screen.
  • Provide a tactile boundary around the allowable area for signatures. If allowing users to sign anywhere on the screen is not feasible, then indicate the allowable area with a tactilely discernible line raised from or etched into the display.
