All Implemented Interfaces:

com.yubico.internal.util.json.JsonStringSerializable, java.lang.Comparable<AuthenticatorTransport>
```
public final class AuthenticatorTransport
extends java.lang.Object
implements java.lang.Comparable<AuthenticatorTransport>, com.yubico.internal.util.json.JsonStringSerializable
```
Authenticators may communicate with Clients using a variety of transports. This enumeration defines a hint as to how Clients might communicate with a particular Authenticator in order to obtain an assertion for a specific credential. Note that these hints represent the Relying Party's best belief as to how an Authenticator may be reached. A Relying Party may obtain a list of transports hints from some attestation statement formats or via some out-of-band mechanism; it is outside the scope of this specification to define that mechanism.

- Field Detail
  - USB
```
public static final AuthenticatorTransport USB
```
    Indicates the respective authenticator can be contacted over removable USB.
  - NFC
```
public static final AuthenticatorTransport NFC
```
    Indicates the respective authenticator can be contacted over Near Field Communication (NFC).
  - BLE
```
public static final AuthenticatorTransport BLE
```
    Indicates the respective authenticator can be contacted over Bluetooth Smart (Bluetooth Low Energy / BLE).
