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. ## Frequently Bought Together - FEITIAN ePass K40 USB Security Key - Two Factor Authenticator - USB-C with NFC, FIDO U2F + FIDO2 - Help Prevent Account Takeovers with Multi-Factor Authentication - FEITIAN iePass K44 Dual-Connector iOS USB Security Key - Two Factor Authenticator - USB-C + Lightning - FIDO U2F + FIDO2 + PIV + MFi - Help Prevent Account Takeovers with Multi-Factor Authentication --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/212346502-feitian-epass-k40-usb-security-key](https://www.desertcart.ie/products/212346502-feitian-epass-k40-usb-security-key) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-10-15*
