The San Jose Mercury News recently reported on an uptick of interest in mobile payment systems that allow consumers to use their phones instead of debit or credit cards. Although not yet widely adopted, the idea is gaining traction.
A customer walks up to a coffee house counter, orders lunch, and pays the bill by lightly tapping the back of her mobile phone against a small receiver next to the cash register. Seconds later, a display message on the box screen approves payment, and the customer receives a text message receipt.
Face it: more often than not, you are on your phone when you walk into the coffeehouse anyway. Welcome to the mobile future!
