RFID key fobs can be made from a variety of materials, including plastic, silicone, metal, and even wood. The specific material used to make an RFID key fob can affect its durability, resistance to weather and environmental conditions, and aesthetic appearance. Some common materials used for RFID key fobs include:
- Plastic RFID key fobs - These are the most common type of RFID key fob and are typically made from ABS or PVC plastic. They are durable, lightweight, and available in a variety of colors.

- Silicone RFID key fobs - These are flexible and easy to grip, making them ideal for use in applications where the key fob may be handled frequently.
- Metal RFID key fobs - These are strong and durable, making them ideal for use in harsh environments or for applications where the key fob may be subjected to rough handling.
- Wood RFID key fobs - These offer a unique and aesthetically pleasing alternative to traditional plastic or metal RFID key fobs.
- Epoxy RFID key fobds - With a transparent epoxy coated on the surface of the RFID keyfobs, like a jelly, beautiful and durable.

The specific number of kinds of RFID key fobs from the material made can be difficult to determine because there are many different materials that can be used, and new materials may be introduced as technology advances. Ultimately, the type of material used for an RFID key fob will depend on the specific application and the requirements of the user.
