The recently released Samsung Galaxy Nexus has brought Near Field Communication (NFC) to the mainstream. Simply pass a PayWave or touch based credit card behind the phone with a good reader app installed and voila, you have credit card data.
We used NFC Taginfo.
Stay tuned, we are not exactly sure what all this data means yet, but it will be interesting to see if we can use my stored credit card data at a shop using the phone. Also I have blurred out numbers above in the pics of my credit card.
