# 蓝牙服务开发概述
+
## 概述
蓝牙技术是一种无线通信技术,可以在短距离内传输数据,该技术规范由蓝牙技术联盟(Bluetooth Special Interest Group, SIG)制定。可以用于连接手机、耳机、音箱、键盘、鼠标、打印机等各种设备。目前蓝牙有两种常见的技术分类:传统蓝牙(BR/EDR)和低功耗蓝牙(BLE)。

# 远端状态订阅开发实例
+
IPC/RPC提供了订阅远端Stub对象状态的机制。当远端Stub对象死亡时,可以自动触发本端Proxy注册的死亡通知。这种死亡通知订阅需要调用指定接口[registerDeathRecipient](../reference/apis-ipc-kit/js-apis-rpc.md#registerdeathrecipient9-1)完成。不再需要订阅时,也需要调用指定接口[unregisterDeathRecipient](../reference/apis-ipc-kit/js-apis-rpc.md#unregisterdeathrecipient9-1)取消订阅。

# @ohos.nfc.tag (标准NFC-Tag)(系统接口)
+
本模块主要用于操作及管理NFC Tag,提供后台读卡和前台应用优先分发两种读卡模式。
后台读卡是指不需要打开应用程序,电子设备通过NFC读取标签卡片后,根据标签卡片的类型匹配到一个或多个应用程序。如果仅匹配到一个,则直接拉起应用程序的读卡页面;如果是多个则弹出应用选择器,让用户选择指定的读卡应用。
前台读卡是指提前打开应用程序,并进入对应的NFC读卡页面后读卡,只会把读到的标签卡片信息分发给前台应用程序。
