In Android, we can have multiple applications to complete the same task. For example, we can have multiple web browsers installed, and when we want to open a web page, the Android system prompts us to choose which application to open; NFC applications are no different. The foreground dispatch system allows an activity to intercept an NFC intent (tag detected or P2P events) and claim priority over other activities that are registered to handle the same intent. This way, when our application is in the foreground, users won't be prompted to choose which application to open, and the intent is sent to our application.

An Intent is a messaging object that describes an operation to be performed and is generally used to start activities, services, and facilitate data exchange among different applications.
