just saw the coolest thing! you can pay for your purchase at starbucks with your iphone! if you use a starbucks card (benefits include free soy milk / free syrups / free drinks), rather than paying with your physical starbucks card, you can instead pay with the starbucks iphone app!
i love the concept!
and i want to see the credit card companies and banks offer the same option! rather than pulling out my credit card, i would instead pull out my iphone and credit card app to pay! no more, amex / visa / mastercard / discover card / bank atm card to carry - you could instead use an app on your iphone / android / other smart phone like device!
places that use rfid readers for access - offices, mass transportation systems - could also offer the option of access with your smartphone!
even your driver's license data could reside in a smartphone app!
other than your smartphone, the only thing you would need to carry is some cash!
which means, we will need an updated tom bihn wallet! one that accommodates your smartphone and some cash!
this may seem silly, but i am really excited about this concept!
