The National Federation for the Blind says its members are unable to sign an e-petition calling for printed material to be more accessible to the visually impaired because of “Captcha” security.

A Captcha is a graphic or sound of a random word or number users must key in to prove they are human.

The petition, on the White House website, has received just 8,200 signatures.

The White House says the site complies with US accessibility standards.
