I’m sorry for the delay in my response here!
Configuring the NFC method requires the Wifi Porter app and an Android mobile device with NFC. I found myself in the exact same situation where I’m strictly Apple product household… our solution? We went to Best Buy, downloaded the Wifi Porter app onto a demo phone and programed the Wifi Porter to our network. (Pro tip, you can program a Wifi Porter even when you’re not on or around the network!) Perhaps an easier alternative is to invite over a friend who has an Android.
Please don’t hesitate to shoot us any other questions. In fact, you can speak directly to the designer/developer behind Wifi Porter by emailing info@tenonedesign.com
I’m not certain where you may have seen a recommendation to purchase an NFC card writer, could you share more about where you saw this recommendation?
