據Gizmodo報道，你有沒有想過揮一揮手就能開門，或者輕輕一碰就能把聯係信息傳輸到手機上？把所有密碼都放在手上怎麼樣？Kickstarter資助的NFC數據環能很快把這些變成現實。

    NFC數據環背後的技術其實十分簡單，無非就是一個鈦金屬環，裏面內嵌兩個NFC芯片。大一點的芯片用于存儲公共信息，小一點的芯片存儲個人信息。這樣使用者就可以使用不同的手勢來分享不同的信息。

    要存儲什麼信息完全取決于穿戴者。就像上面建議的那樣，NFC信號可以執行一些簡單的任務，比如解鎖手機或開門。你還可以存儲各種個人信息，比如你想和朋友分享的網絡鏈接，甚至是你的比特幣。它還可以被設計成鑰匙圈，甚至取代你的汽車鑰匙。當然前提是你的要求能在生產線上生產。

    關于NFC數據環最酷的地方是它的發明者John McLear很開放。除了通過Kickstarter以每件38美元的價格出售數據環外，McLear還把設計這個數據環的CAD文件放在裏面，希望人們修改設計或者自己3D打印。在發售將近一個月後，數據環銷售額剛剛突破4.6萬美元的目標。McLear和公司說他們希望使用所有通過Kickstarter得到的錢來擴大生意，改善數據環的設計，然後發明新產品。

    目前這個數據環可以和任何安卓程序一起工作，破解後也可以和Windows和黑莓設備工作。目前還沒有關于iOS的消息，但是由于蘋果產品並未配備NFC功能，目前實現起來應該比較難。在近期，他們計劃開發不銹鋼版本和Windows應用。在長期，McLear希望希望提供不同顏色的內嵌部分（包括木質的），還要設計全黑的“秘密投彈手”數據環。因為讓可穿戴設備變得時尚肯定是個好主意。

    This NFC-Enabled Ring Stores Your Personal Data On Your Fingertips

    Have you ever wanted to wave your hand to unlock a door or transfer your contact information by simply touching a phone? How about keeping all of your top secret passwords at arm's length, literally? Well, with this Kickstarter-funded near field communication-enabled ring, all that could soon be possible.

    The technology behind the NFC ring is strikingly simple. It's nothing more than a titanium band and two inlays with NFC-ready chips in them. There's a big one on the top of the ring for public information and a smaller one on the inside for private information. This is designed to enable the wearer to use different types of hand gestures in order to share different kinds of information.

    What that information might be is totally up the wearer. As suggested above, the NFC signal can perform simple tasks like unlocking a smartphone or your front door. You can store all kinds of personal data including URLs that you want to share easily with your friends, and even save the code for your Bitcoin fortune. It can be programmed to work as your key fob and actually serve as a replacement for your car's ignition button. This is all assuming the rings make it off of the assembly line in working order, of course.

    One of the coolest aspects of the NFC ring project is how open creator John McLear is about how he builds the rings. In addition to selling the rings for $38 a piece through a Kickstarter—they just reached their goal of $46,000 with nearly a month to spare—McLear put the CAD files for the ring so people can hack the design and 3D print rings themselves. McLear and company say they plan to use any and all Kickstarter money they raise to expand the business, improve the rings and come up with more offerings.

    For now, the ring will work with an Android app, although it can be hacked to work on Windows and BlackBerry devices. There's no word on iOS compatibility, but since Apple products don't have NFC capabilities, we're guessing it's pretty far down the pipeline. In the near term, the goals include things like offering a steel option and developing a Windows app. In the long run, McLear hopes to offer different colored inlays (including wood) and to design an all black "stealth bomber" ring. Because it always helps to make wearable computing fashionable too.
