NFC Shortcuts (aka NFCLauncher) is one of my most used BlackBerry applications. NFC Shortcuts is the first NFC app for BlackBerry that allows you to launch apps or shortcuts conveniently by tapping your BlackBerry® to a NFC tag. The NFC applications are endless from enabling to disabling WiFi to checking in to Foursquare and may more.
Google “nfc-tag-tasks-ideas-all” to read more about this app.
For example when you get home, you can just tap a NFC tag at the entrance door and your BlackBerry® will turn off the cellular radio, turn on WiFi (home network), turn off Bluetooth (used for handsfree in the car), and even send an SMS to your family members (not at home) notifying them that you are home (This example requires ShortcutMe app that has macro feature).
Or you can tap a tag on your nightstand to set the BlackBerry® into bedside mode. Tap it again in the morning to take the device out of bedside mode.
Any NFC tag that BlackBerry OS can read is supported by this application but the best tags are none programmed Mifare Ultralight tags that are both cheap and can be found in different shapes and forms.
