Creative triangulation for mobile payment systems

Now, this is interesting. A mobile payment system that supports an existing paper-based system. (more from Daniel today, he's on fire ;). Most ticketing systems now support UPC code reading for tickets purchased and printed at home. Now you can buy your tickets on your cell phone and have the UPC scanned from your phone.

Payment systems, just like good authentication system are triangular. Even cash has a dotted line triangle back to the faith and trust in the government that backs them. This system is potentially more secure than contactless payment systems because you can use strong public key encryption and two-factor authentication on the cell phone. With WiKID you could also present a one-time passcode for use in web-based payments.
