samples: NDEFReader not found in window

Hi, I seem to have some issue detecting the NFC feature support using the code snippet: if ('NDEFReader' in window) { /* Scan NFC tags */ } if ('NDEFWriter' in window) { /* Write NFC tags */ }

However, when I visit https://googlechrome.github.io/samples/web-nfc/ on the same browser it seems to work.

Any idea what may be the issue here?

I’ve figured the issue, seems that you need to enable Experimental Web Platform features flag on the Chrome Beta browser as well. Found out from this commit: https://github.com/GoogleChrome/samples/commit/bb1c58ef8ede07e56c8ef075d0b477a917764782

FWIW, the content attribute which should contains the token is empty at https://webnfc.now.sh/

Using Chrome Beta v81.0.4044.42, Web NFC is available for me at https://googlechrome.github.io/samples/web-nfc/ Note that it not used on this website, you need either to enable the flag OR request a token for origin trial
