I have found more losted mobiles than I wanted to. The ones I found, I could go into their systems and see their contacts. I received calls from their friends asking where they were. Now, imagine if you left your mobile somewhere or someone stole it. That person can take the cell wave it at a machine and voila, they have your bank account and can buy all they want with no help of loans online for unemployed. This payment system isn't for me sorry. Now, if there was a "fingerprint" way of telling who was holding the phone and it would unlock for the fingerprint I would feel better about having my credit cards and financial business in the phone.
