There are several projects working on mobile crypto payments.

One project doing that is Tip. Tip will change the way cryptocurrency payments are sent around the world. The Tip blockchain uses usernames instead of crypto addresses for transactions, and you can find other people by searching by username. Usernames on there work just like twitter handles.

Full disclosure, I am the founder of the Tip Blockchain project.
