Review: The USB-C part of it works. But not the NFC - it did not work with my iPhone. Other NFC keys like Yubikey and Identiv uTrust worked with my iPhone. The iPhone did not detect the K40 over NFC.
Review: Bought to replace yubikey(tm) that i lost. This looks better on my keychain. Works exactly as yubikey(tm) to secure my laptop and accounts. But much less expensive. I replaced the 5 NFC with this. The USB-C works with phone and laptop no need to use the NFC although It has it.

## Questions & Answers

**Q: This usb-c key says it has nfc. does this mean it can be used to authenticate a device wirelessly, or does it still have to be plugged in?**
A: This Security Key (Feitian ePass K40) absolutely DOES work via NFC. I can confirm this as I have used it with NFC on my phone many of times as it is very convenient & very easy to do. It's slightly faster than plugging it in via USB as well, but either way works fine. I personally prefer using it with NFC. I am not sure where Sgt. Scott got his answer from, but maybe his phones NFC isn't working because as I said before, this Security Key most certainly does work with NFC. I can add a video to my answer showing me doing so if you would like a visual confirmation, but I assure you, it does work. It specifically states it in the item title as well as in the item description. NFC is one of the main reasons I chose this particular security key. I personally have 3, this one, which is the (ePass k40), I also have the (ePass K9), & the (ePass K40 Plus) which is the same as this one but also has PIV functions. All 3 of them have NFC capabilities & all 3 work flawlessly via USB & NFC.

**Q: Does it work with the ipad pro 2018 model? it does not state that it supports ios.**
A: No, uses usb c connector

**Q: Does it work with bank of america?**
A: Of course, I use this at Bank of America.

**Q: Does it work in password Managers like Keepass?**
A: For me, this doesn't work at all with almost no helpful documentation.
