我可以在组内发送消息到一个单一的设备iBeacon显示？ [英] Can I send a message to a single iBeacon device within a group?
问题描述
我只是读了上iBeacon显示，我可能想使用它目前，我参与了一个项目，我现在从它理解是这样的：
I'm just reading up on iBeacon, and I might want to use it for a project I'm currently involved in. What I currently understand from it is this:
简单地说，一个iBeacon显示设备广播消息给谁就给谁是
在范围内。这个消息包括发送方的MAC地址，并
从它的信号的强度，接收器可以计算出
距离。 iBeacon显示设备可以是发送者，接收者或两者
Simply put, an iBeacon device broadcasts a message to whomever is within range. This message includes the sender its mac-address, and from the intensity of its signal, the receiver can calculate the distance. iBeacon devices can either be senders, receivers, or both.
1）首先，这是正确的？
其次，维基百科的页面上，我读了它可以使在销售终端（POS）点金。因为我明白，这基本上是一个非常本土化的广播服务，我只是想了解类似的东西会工作。
Secondly, on the wikipedia page I read that it could enable payments at the point of sale (POS). Because I understand that it is basically a very local broadcast service I'm just trying to understand how something like that would work.
2），将在支付的情况下，存储或客户进行付款？
3），以及如何将你prevent其他附近的设备拿起支付报文？
4）最后，是否有可能发送iBeacon显示消息给其MAC地址识别只有一个iBeacon显示设备？
任何提示和见解都非常欢迎！
Any tips and insights are very welcome!
推荐答案
启用移动支付是东西，你可以的建立在的iBeacon显示技术上面的例子。但 iBeacons本身是很简单的构建块，只会是一小片一解。这是href=\"http://developer.radiusnetworks.com/2014/01/10/ibeacon-misconceptions.html\" rel=\"nofollow\">常见的误解，一个来混淆的什么iBeacons办本身的用的什么可以iBeacons完成的
Enabling mobile payments is an example of something you could build on top of iBeacon technology. But iBeacons themselves are very simple building blocks that would only be a small piece of a solution. It is a common misconception to confuse what iBeacons do themselves with what can be done with iBeacons.
在交付使用的情况下，iBeacon显示将执行的唯一功能是唤醒支付应用程序，并告诉它的手机销售点附近。 （随着销售点的具体数字标识符。）这就是它！这是所有的iBeacon显示一样。其他必要的一切都将与其它软件来构建。
In the payment use case, the only function the iBeacon would perform would be to wake up the payment app and tell it the phone is near the point of sale. (With a specific numeric identifier for the point of sale.) That's it! That is all the iBeacon does. Everything else necessary would be built with other software.
有很多可能的答案您关于支付处理其他问题，但他们没有具体涉及iBeacons。通常情况下，一个移动支付系统将需要输入一PIN以确认付款。因此，使用iBeacons一个应用程序可以简单地显示一个选项，以支付任何设备与支付应用程序，是销售点的几英尺。
There are lots of possible answers to your other questions about payment processing, but they are not specifically related to iBeacons. Typically, a mobile payment system will require entry of a PIN to confirm payment. So an app using iBeacons could simply display an option to pay to any device with the payment app that is a few feet of the point of sale.
在最简单的实现，手机会质疑支付服务器这样的消息：我靠近POS终端与iBeacon显示标识＃12345。是多少付款？和服务器可能包含$ 23.95的消息，这将在手机的屏幕上显示响应。在这个实现中，用户将验证屏幕上的量，并输入一PIN以进行确认。该确认将是安全机制确保错误的设备不支付错误的顺序。其它更复杂的实现是可能的，但同样它们并不严格相关iBeacons。
In the simplest implementation, the phone would query the payment server with a message like "I am near POS terminal with iBeacon identifier #12345. How much is the payment?" And the server might respond with a message like "$23.95", which would be displayed on the screen of the phone. In this implementation, the user would verify the amount on the screen and enter a PIN to confirm. This confirmation would be the security mechanism ensuring that the wrong device does not pay for the wrong order. Other more sophisticated implementations are possible, but again they are not strictly related to iBeacons.
另外两个说明：
-
而一个iBeacon显示的确发送它的蓝牙MAC地址，这通常被忽略。事实上，iOS的块读此MAC地址，所以该平台上没用的。相反，应用程序依赖于特定iBeacons三部分组成的标识符：ProximityUUID，主要，次要
While an iBeacon does transmit its Bluetooth Mac address, this is typically ignored. In fact, iOS blocks reading this Mac address, so it is useless on that platform. Instead, applications rely on a three part identifier specific to iBeacons: ProximityUUID, Major, Minor.
有没有办法只有一个设备看到iBeacon显示做。这是一个开放的无线传输在其约一切可见。 150英尺范围。
There is no way to make only a single device see an iBeacon. It is an open radio transmission visible by everything in its approx. 150 ft. range.
