Neither Safari nor Mozilla will support these features. WebUSB is considered harmful by both. As is WebNFC if I remember correctly. WebHID has the same concerns as WebUSB.

See, for example, https://github.com/mozilla/standards-positions/issues/459 https://github.com/mozilla/standards-positions/issues/459
