Idea of RFID Signal Icon
This is a logo with a small filled in circle in the very center. To the left and to the right of this circle are three sets of lines, each a bit longer than the one before it closest to the circle. These lines curl to wrap around the circle.
This RFID Signal icon has Android KitKat style
. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
