Blogs have called it the end of the wallet but many people don't believe this is achievable by 2015. We will just have to wait and see. Personally I believe that digital currency will only gain relevance in the years to come and as we explore the topic by means of technology, scales might shift to different ways of measuring value and spending habits.
Mobile certainly pays a part here. According to the latest 2010 numbers released by CTIA, the US has over 300M Wireless Subscriber Connections and with a population of over 307M people ('09) you can bet that nearly everyone in the country has a mobile phone! And with smartphone penetration reaching 50% coupled with services like PayPass, PayPal, Google Wallet and others, digital currency will become a reality faster than most of us think.
Many of us might not be able to get rid of our wallets just yet: where will you keep your driver licence? Maybe we should call the DMV and let them know that the future is here and now and your licence should live as an online document and not a piece of plastic. I am sure looking forward to being one of the first to get rid of my credit cards and my cash to use my mobile device to pay for parking, food, etc.
Remember when the ATM card was first introduced? I do not doubt that very soon paying with plastic will become the equivalent of slowing down the grocery line to pay with a check.
