安乐施会不支持选择性的最惠国指挥?
原标题:Android HCE does not support select MF command?

我们正在开发一个基于安康的仪器。 我们发现,该中心利用以援助为基础的机制,将通信传递给具体信息。 这意味着,如果我想启动我的评估,第一任指挥官必须是以名字指挥的选任。

这是对运输领域的一大限制。 在运输方面,许多分遣队通过名称指挥作为首批指挥员,打赢了一批塞诺。 相反,它们会派一个SélectT MF(00A40000023F00)作为第一个指挥。 因此,人道主义应急中心可以在这种情况下开展工作。

Is there any plan to add default select feature? Or do we have some other solution to support this use case?

最佳回答

安德列斯利用基于国际开发署的路径选择机制,向具体应用(商品安全局的申请或SE传阅器)发送卡普林素。 这也是全国渔业委员会论坛设计的主要手段,用以支持针对单一NFC装置的多份独立心素养申请。

AID-based routing requires the first command to be a SELECT (by DF name/AID) command:

00 A4 0400 <Lc> <AID> [<Le>]

这对于区分不同的应用是必要的。 否则,Anderson将无法向适当的HCE服务机构发出通信。

然而,这还阻止了在成功选择申请之前的任何东西(例如使用SélectT(档案名称等)指挥选择主档案)。 如果允许这样做,那么安康将无法知道该中心的申请是谁负责处理这一指挥。 因此,不可能收留所有需要一个装置的总档案的多个电子计算机应用系统。 因此,我并不期望很快会得到支持。

关于其他相互适用平台,也存在同样的问题。 例如,典型的Java卡明卡片也没有总档案。 在这些平台上,通常通过允许在第一次选举前处理所有通信的缺席选择申请(由国防军/国际开发署的名称)来解决这一问题。 只有当这种机制在未来版中出现时,我们才能猜测。 我不会指望这样做。

如果根植装置是一种选择,那么你可能能够利用Xposy这样的框架,调整东岸委员会系统服务,向一些拖欠的中西部非洲经济共同体服务发送通信。

For transportation, Visa use its application qVSDC app as offline solution. It provides specific public keys for offline data authentication to limit those transactions on transportation. So default select is A0000000031010 for Visa not a specific AID for transportation. But Visa provides multi AID support meaning that you can develop 2. application to use on transportation. You must personalize your app to response specific "Select AID" command.
