Interact with NFC Tags on a Mobile Device

A Lightning web component can use a device’s native NFC functionality to read, erase, and write to NFC tags. When an NFC operation is successful, the text data extracted from the NFC tag or a simple success message is returned to the Lightning web component that invoked it.

NFC operations are performed locally on the mobile device, and don’t need a network connection. However, NFCService requires access to platform-specific APIs that are available only within compatible Salesforce mobile apps.

NFCService does not and cannot function when running in a web browser, whether on a desktop or mobile device.

Important

NFCService User Experience

Your component can deliver any user experience you desire, but there’s a common flow for any component that interacts with NFCs.
Use the NFCService API

To develop a Lightning web component capable of interacting with NFCs, use the NFCService API.
NFCService Example

Here’s a basic example of a Lightning web component that uses NFCService to parse text data from an image.
Compatibility and Requirements

NFCService is a JavaScript module that provides an API to Lightning web components to make mobile hardware and platform (operating system) features available in JavaScript. It requires access to device hardware and device platform APIs. This access is only available when NFCService runs within a compatible Salesforce mobile app. It does not and cannot function when running in a standard web browser, whether the browser runs on a desktop or mobile device.
Considerations and Limitations

Consider these guidelines and limitations when developing features that use the NFCService API.
