According to Engadget, Radio Shack is prepping for NFC payments via Google Wallet on September 1st.
Near Field Communication, that's what NFC stands for, is a protocol that can be used for contactless mobile payment. What we in the mobile crazed world want is to be able to use our phones to buy things. And Google Wallet is one of a dozen or so mobile payment systems out there that will soon be competing for our money.
However, mobile payment isn't about to become ubiquitous overnight. This will take a long long time for the ramp up to take place. Most devices on the market do no support NFC and payments such as the ones I use via Starbucks, requires no NFC but you just need to let a special scanner take a peak at your screen.
Regardless, it's great to see Google leading this effort. Google, as well as others, knows that this is a huge market. Most major credit card companies, VISA, Mastercard, Discover, all have their own payment plans.
And here in the US, we are definitely behind the times in the industry. The Japanese have been able to use their phones to make payments (like train fares) for years.
