Screen reader
Also known as: JAWS, NVDA, VoiceOver, TalkBack
A screen reader is software that reads what's on a screen out loud (or sends it to a Braille display) so blind and low-vision people can use a computer or phone.
In plain terms
Instead of looking at the screen, the user listens. The screen reader announces headings, links, buttons and text, and lets the person move around with the keyboard or touch gestures. Popular ones are JAWS and NVDA on Windows, VoiceOver on Apple devices, and TalkBack on Android.
Why it matters
Screen readers only work well when a page is built with proper structure — real headings, labelled buttons, and alt text. If you've only styled things to look right visually, a screen reader user gets a confusing, unusable mess. Testing with one is the best way to catch problems automated tools miss.
Turn on VoiceOver (Cmd+F5 on a Mac) and try to complete your checkout using only the keyboard. If you get stuck, so do your users.
