The Premium RFID key fobs look much nicer than the usual tear-shaped plastic RFID key fobs, and are very convenient RFID transponders for charging electric vehicles, unlocking the doors, and identify users in various other RFID applications.
The upper part of the premium key fob is made of stainless steel, and the lower part is made of an imitation black leather plastic material. The total dimension including a ring is 85 x 35 mm.
They are robust and well made, so they will serve their purpose for a long time.
