This is a drawing of a hand pressed against a screen. There is a box where the hand needs to be placed and some sort of the line scanning across to the hand.
This Palm Scan icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
