NFC指环让你在指尖轻松分享数据

据Gizmodo报道，你有没有想过挥一挥手就能开门，或者轻轻一碰就能把联系信息传输到手机上？把所有密码都放在手上怎么样？Kickstarter资助的NFC数据环能很快把这些变成现实。

NFC数据环背后的技术其实十分简单，无非就是一个钛金属环，里面内嵌两个NFC芯片。大一点的芯片用于存储公共信息，小一点的芯片存储个人信息。这样使用者就可以使用不同的手势来分享不同的信息。

要存储什么信息完全取决于穿戴者。就像上面建议的那样，NFC信号可以执行一些简单的任务，比如解锁手机或开门。你还可以存储各种个人信息，比如你想和朋友分享的网络链接，甚至是你的比特币。它还可以被设计成钥匙圈，甚至取代你的汽车钥匙。当然前提是你的要求能在生产线上生产。

关于NFC数据环最酷的地方是它的发明者John McLear很开放。除了通过Kickstarter以每件38美元的价格出售数据环外，McLear还把设计这个数据环的CAD文件放在里面，希望人们修改设计或者自己3D打印。在发售将近一个月后，数据环销售额刚刚突破4.6万美元的目标。McLear和公司说他们希望使用所有通过Kickstarter得到的钱来扩大生意，改善数据环的设计，然后发明新产品。

目前这个数据环可以和任何安卓程序一起工作，破解后也可以和Windows和黑莓设备工作。目前还没有关于iOS的消息，但是由于苹果产品并未配备NFC功能，目前实现起来应该比较难。在近期，他们计划开发不锈钢版本和Windows应用。在长期，McLear希望希望提供不同颜色的内嵌部分（包括木质的），还要设计全黑的"秘密投弹手"数据环。因为让可穿戴设备变得时尚肯定是个好主意。

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 Wi
