This RFID Tag 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 4,600 icons, all in the same style and quality.
It looks like the outline of a computer chip of some sort. It is mostly square, but on the left corner it's straight. There are then lines going around the inside that meet at a smaller square in the middle.
