Since the previous two approaches are not so userfriendly,
the other possibility is Mobile Wallet as
software in mobile phones. This approach provides
friendly GUI, so that users can perform transactions
very easily and without mistakes. The most
important advantage of this approach is application
level end-to-end security. With this approach
complete and integrated security system, including
authentication, authorization, confidentiality and
integrity, which is essential for every financial
transaction system, can also be provided.
