What’s the use case for NFC?
- mike-cardwell 11y agoUsing PGP on your smartphone without giving it access to your PGP key - https://grepular.com/An_NFC_PGP_SmartCard_For_Android https://grepular.com/An_NFC_PGP_SmartCard_For_Android - That's how I use it anyway.
- justinjlynn 11y agoFor usage with mobile applications, where NFC is typically available but USB Host is not, I would imagine.
- JohnTHaller 11y agoOn Android, you typically have USB host (at least on any phone that someone interested in this tech would buy). On iOS it's moot since NFC is gimped and can't be used by apps.
- lorenzhs 11y agoMost people don't carry the necessary cable around with them, though. NFC doesn't require any additional hardware. I use it for generating 2FA codes, Yubico Authenticator works like Google Authenticator except that it requires touching the YubiKey to the phone before it shows the 2FA codes. The codes are computed on the YubiKey: https://github.com/Yubico/yubioath-android/blob/63387c02a39be5d22e688aa9305a54eed1f40916/app/src/main/java/com/yubico/yubioath/model/YubiKeyNeo.java#L317 https://github.com/Yubico/yubioath-android/blob/63387c02a39b...
