Cellphone wallet

I believe mobile devices will replace conventional wallet including cash, loyalty cards, ticketing card for public transportation etc. One tool may be used for a lot of purposes with same user experience.Are you ready for use mobile phone to do payments when it s possible? What are the most important situations where you want to use mobile phone for payments? I think that Single Sign - On authentication with mobile phone can enlarge user experience in new level really.
