Web NFC API
Limited availability

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The Web NFC API allows exchanging data over NFC via light-weight NFC Data Exchange Format (NDEF) messages.
Note: Devices and tags have to be formatted and recorded specifically to support NDEF record format to be used with Web NFC. Low-level operations are currently not supported by the API, however there is a public discussion about API that would add such functionality.
