Yoti

Yoti is identity-verification software widely used on websites based in the United Kingdom, but not very often in North America and elsewhere.

Why it Sucks

 * 1) The software is absolutely terrible at scanning passports, driver's licenses, and faces. It often doesn't recognize them and will therefore prevent the user from using the Yoti-enabled site. Worse, it will sometimes give an error stating the photo is being used by somebody else.
 * 2) Bad customer service. Support ticket responses are unhelpful. Some requests require a video call, resulting in privacy concerns.
 * 3) Many adult websites end up implementing it for identity verification, due to an EU law designed to prevent minors from being exposed to obscene content.
