Idea of NFC C Icon
There is a square with rounded corners. At the bottom on the inside of the square about a quarter-of-the-way from the corner, a line goes up almost to the top, then it comes down to the right at a 45 degree angle for a length equal to half of a side of the square.
This NFC C 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 6,200 icons, all in the same style and quality.
