CAPTCHA Icon in iPhone Style

This is a CAPTCHA icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
This icon is used a lot to verify you are not a robot. It is a reduced rectangular box that is filled with a white background and floating letters and numbers inside it.
