Cellphone Tech

What if we didn't have to use our keys to get into our houses, or take out a wallet to pay for something at the register or even show someone your actual ticket at a ball game? What if you could take all those with you simply on your phone.

The cell phone has morphed into an almost miniature computer with its ablity to play music, check email, and even work on spreadsheets on the go. However, as it slowly replaces the computer on the go, it might soon be changing the amount of things you have to carry with you; generally, your phone, wallet and keys. Of course this assumes that you dont leave your key under the doormat or the rock beside the door.

Much like how American Express has ExpressPay or MasterCard has Pay Pass, we might soon just have to wave our cell phone over credit card machines and our items will be paid for, thanks to RFID. The picture below depicts the concept.


Mobile wallets are not something new, as people have tried to find more ways to have less things in their wallets. Consolidating things might also be a sort-of green movement, since you would no longer need a wallet and all the associated production costs.

If you really wanted to have a "mobile credit card, you can simply cut up an existing card with an RFID chip and put it between the battery cover and the battery of your phone. That might actually work well as a short term solution. Expect to see more cellphone-wallet combination technology within the next 5 years.
