What is an NFC Inlay
An NFC inlay is the most basic and cost-effective type of NFC tag. NFC inlays can be used alone or embedded and converted into other products by product manufacturers. The surface material of an NFC inlay is plastic, not paper, which makes them water resistant; however, they have no protective structure and are subject to damage due to bending or compression. Wet NFC inlays have adhesive backing like NFC stickers, but cannot be printed with color artwork like NFC stickers can. NFC inlays are delivered on a roll or in strips for small quantities. GoToTags designs NFC inlays for high performance and very large quantities of NFC inlays are kept in stock for short lead times.
What Is a 13.56MHz Aluminum Antenna NFC Dry Inlay?
A 13.56MHz NFC Dry Inlay consists of three primary components:
| Component | Description |
|---|---|
| Aluminum Etched Antenna | A precisely designed aluminum coil responsible for wireless communication and energy harvesting |
| RFID/NFC Chip | Stores data and communicates with NFC readers or mobile devices |
| PET Substrate | Provides mechanical stability, flexibility, and durability |
The antenna receives electromagnetic energy from an NFC reader or smartphone. The chip uses this energy to activate and transmit stored information back to the reader.
Because the inlay does not include adhesive layers, it is called a “dry” inlay. Manufacturers can add their own adhesive materials depending on the final application.
Key Features of Aluminum Antenna NFC Dry Inlay

How Does a 13.56MHz NFC Dry Inlay Work?
A passive NFC dry inlay does not require an internal battery. Instead, it receives energy from an external NFC reader.
The communication process works as follows:
- A smartphone or RFID reader generates a 13.56MHz electromagnetic field.
- The antenna coil captures the energy from the magnetic field.
- The NFC chip becomes powered and processes stored data.
- The chip sends information back to the reader through electromagnetic communication.
This passive operating principle makes NFC dry inlays maintenance-free and suitable for long-term use.
