Plastic Out, Smartphones in

Who needs a wallet? Certainly not to carry business cards, pictures, or even credit cards. The smartphone can do it all. Exchange business card information, hold airline boarding info, and now to purchase goods and services. "AT&T Inc. and Verizon Wireless, the biggest U.S. mobile carriers, are planning a venture to displace credit and debit cards with smartphones, posing a new threat to Visa Inc. and MasterCard Inc., three people with direct knowledge of the plan said." How easy is that.

So my biggest question is what to do when the battery runs dry. I heard recently that airline counters keep universal cords for smartphones if the need arises for extra power to get the boarding info of the phone. What happens when there is no power? I love that the smartphone is gaining even more usage making it an even more invaluable device to have. So now more work is needed to make the battery life last even longer. When your phone needs to be recharged nearly every night, it makes the need for alternatives a necessity. A piece of hard plastic may run out of money, but not out of power.
