+#### Binary Token
+
+V3 and V4 Token can be transmitted in a binary format when applicable (for example when transmitting via NFC).
+For this the serialised token is prepended with a prefix and a version byte.
+
+```
+utf8("craw") || utf8(<token_version>) || <serialised_token>
+```
+
+- Token V3 Version: `utf8("craw") || utf8("A") || cbor(token_object)`
+- Token V4 Version: `utf8("craw") || utf8("B") || cbor(token_object)`
