Our Web SDK is currently not able to perform NFC authentication. The reason for this is that browsers do not provide native support for NFC. Browser makers will check whether this is a desirable feature. If there is universal support for NFC in the browser, we would of course like to enable NFC authentication in our Web SDK as well.
We are working hard to introduce an alternative authentication feature in the near future. If you want to authenticate eIDs and/or ePassports in the meantime, please use our Mobile SDKs for Android and iOS.
