The NEO is a Yubikey v3. It supports NFC. v3 is the last FOSS one, but it does not support FIDO2. If you want a YubiKey with NFC which supports FIDO2, you need a YubiKey 5 (NFC version). Or a Solo with NFC (the Solo support FIDO2 and is FOSS).

I happen to have one of the InCharge chargers as keychain [1] and what is interesting is that it is 3 chargers in one: one's always USB-A, other one is either USB-C or microUSB/lightning. So they combine microUSB with lightning on the same connector. I wonder why YubiCo did not go with a similar design.
