The WebNFC API seems like it makes it possible to read and write text between devices.
However, when I tried to read/write between phones using this website: https://nfctools.net/
The phone vibrates, but then I get the error NotSupportedError:
There is no NFC adapter compatible with Web NFC, or the available NFC adapter does not support pushing messages, or connection can not be established.
Is the limitation of the protocol, the web api, or just my phone?
