NFC may replace our wallets in like 5 or 10 years, perhaps. Right now? Nope. You've got your Drivers License, IDs, badges, Debit Card (you can't get cash with your phone, as of yet), Health Insurance Card, and Cash in your wallet. So the purpose of NFC is to start revolutionizing your payment options, but without the infrastructure, the alternative of using your plastic is no less inconvenient if you're forced to carry a wallet with you anyway. /Rational thought PS. iPhone 5S will have NFC next year. And Apple is going to hype it like crazy.
