Is there an app that associates a certain action to a arbitrary NFC tag?

Question

I'm using the NFC Task Launcher for launching actions stored on my own tags. This works fine.

What I'm searching for is an app that associates a certain action with an arbitrary tag. An example: my company ID card has an NFC tag. This tag cannot be changed by me. But I want to activate a "At Work" profile when I scan that tag.

So, the actual action is NOT stored on the tag but on the phone and gets triggered by reading that tag.

Is there an app that I could use for that?

Answer 1

If you don't mind a small amount of simple programming, it is pretty easy to trigger actions from NFC using Microsoft's ON{X} app (yes, bizarrely this is a Microsoft app that's only available on Android).

As long as you've already got the hardware support, this lets you trigger a whole lot of actions with an NFC tag, with an absolutely minimal amount of simple scripting. See their recent blog entry on NFC for some of what you can do.

Answer 2

The answer of CAThrawn pointed me to the right direction (thanks for that!): it's possible with ON{X} and a few lines of custom code. There you go:

function messageSentCB(err){
  if(err != undefined) {
    var m = device.notifications.createMessageBox('mail sending failure');
    m.content = err;
    m.show();
  }
}

function sendMessage(){
  var _to = "<recepient>";
  device.messaging.sendMail({to:_to, subject:'arrived at work', body:':-)'}, messageSentCB);
}

device.nfc.on("found", function(signal) {
  var workid = "id-of-my-tag-at-work"; // id of my tag at work
  var id = signal.id.toArray().join("-");

  if(id == workid){
    var notification = device.notifications.createNotification("At Work");
    notification.vibrate = false;
    notification.show();

    device.network.wifiEnabled = true;          // enable WIFI
    device.bluetooth.enabled   = false;         // disable BT
    device.audio.ringerMode    = 'vibrate';     // silent mode on
    device.network.on("wifiOn", sendMessage()); // send mail once connected
  }
});

Works great for now. I'm going to dive into the ON{X} API a bit in order to toggle the state and so disable settings again once I want to leave work.
