We used to work together <a href=" http://www.mens-app.es/existe-el-sindrome-post-finasteride/ ">billigere cialis levitra viagra</a> I agree. Where is the convenience? I could perhaps see one or two working in conjunction with cards, just as a cash replacement or ability to load a prepaid card primarily for the unbanked or uncreditworthy but slow to go beyond this. I do disagree there will only be one unless the one actually supports multiple providers. Customers and merchants are wary of monopolies and even credit cards would not have made it without the competition of Visa and Mastercard. The best hope any of these have at making it is providing common access for others.
