I recently read a blog about how people's phones are going to make wallets extinct. The only thing they could figure out was how to cart around your ID and cash. They make cell phone cases for that.
The truth is Near Field Communication (NFC) is going to pretty much make credit cards an unnecessary thing. For those not familiar with NFC, basically your phone can send out a signal to a receiver. In order for the communication to occur the signal sender and signal receiver need to be very close. Like 3cm close. Hence the Near in NFC.
The next generation of smartphones are going to be equipped with NFC. The technology is already gaining traction in Asia, where people can swipe their cell phones at Subway turnstiles. You'll be able to pay for groceries, gas, magic sets, and other essentials with your phone.
