-* ``android.intent.action.VIEW`` with URIs following the ``openpgp4fpr`` (OpenPGP version 4 fingerprint) schema.
-* For example: ``openpgp4fpr:73EE2314F65FA92EC2390D3A718C070100012282``.
-* Compatible with Monkeysphere's and Guardian Project's QR Codes
+## QR Code format
+* QR Codes contain an Uri with the ``openpgp4fpr`` scheme and the full fingerprint, such as ``OPENPGP4FPR:73EE2314F65FA92EC2390D3A718C070100012282``
+* The Uri is fully uppercase to use the more efficient [alphanumeric encoding](https://en.wikipedia.org/wiki/QR_code#Encoding) that does not support lowercase letters.
 * Only full fingerprints are supported, not key IDs. After scanning OpenKeychain allows for certification of keys and this is only secure with full fingerprints.
+* OpenKeychain also supports opening ``openpgp4fpr`` Uris with full fingerprints via Android's ``android.intent.action.VIEW`` Intent

-## About `openpgp4fpr` (copied from https://github.com/effigies/openpgp4info)
+In 2010, the [Monkeysphere](http://web.monkeysphere.info/) project [introduced](http://permalink.gmane.org/gmane.comp.security.monkeysphere/592) the `openpgp4fpr:<FINGERPRINT>` scheme for sharing OpenPGP version 4 key fingerprints, where `<FINGERPRINT>` is the full 40 hex character fingerprint of a primary key, and has since been adopted in vCards for sharing public keys.

+Perhaps more significantly, several Android applications ([APG](https://play.google.com/store/apps/details?id=org.thialfihar.android.apg)/[OpenKeychain](https://play.google.com/store/apps/details?id=org.sufficientlysecure.keychain), and the Guardian Project's [GnuPG port](https://play.google.com/store/apps/details?id=info.guardianproject.gpg)) now accept this scheme as a means of quickly exchanging public keys via QR codes. The Android "intents" interface paves the way for `openpgp4fpr` URIs to become increasingly common.
