Idea of Fingerprint Icon
This looks like a zoomed-in finger print. There are many lines that start in the bottom right, curving up and to the left, and then ending in the bottom left. There's many breaks in the lines.
This is a Fingerprint 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 13,900 icons, all in the same style and quality.
