Chrome, nfc-list and ACR122

[glococo]

Hi everyone. I want to work in desktop with the ACR122 nfc pad but It seems to not be detected by Chromium, Chrome (Beta/Dev) in Ubuntu.

My current setup seems to work from console:

guillermo@lab:~$ nfc-list -v
nfc-list uses libnfc 1.7.1

In Chrome I get in web-nfc sample:

User clicked scan button
Argh! NotAllowedError: NFC permission request denied.

Any help is really appreciated.

Web NFC is only supported on Android. NFC is no longer a default component of a PC (according to Intel). QR is nowadays the recommended solution for interacting with an external device and the desktop Web.

Indeed, the current implementation of Web NFC is for Chrome on Android.

There has been some work done to use NFC middleware on Linux to implement Web NFC (e.g. using neard) but in the end we have focused on doing the first implementation on top of the more mature Android NFC API.

That being said, the doors are open for other Web NFC implementations. It would be really nice if someone would pick up that work (neard maintenance and eventually Web NFC implementation on top of it).

Closing as this is not spec related
