Write NDEF message multiple times to same tag?

Question

On Android, as soon as an NFC tag gets in proximity of the phone, the system delievers an intent to my application that contains an objects that allows me to read and write

Answer 1

I'm able to write to a tag more than once without separating it from the phone and tapping it again. See following code for example:

ProximityDevice device = ProximityDevice.GetDefault();
device.SubscribeForMessage("WriteableTag", WriteableTagHandler);


private void WriteableTagHandler(ProximityDevice sender, ProximityMessage message)
{
    var message1= Encoding.Unicode.GetBytes("http://1stUrl.com");
    var message2 = Encoding.Unicode.GetBytes("http://secondUrl.com");

    sender.PublishBinaryMessage("WindowsUri:WriteTag", message1.AsBuffer(), (s, e) =>
        {
            s.StopPublishingMessage(e);
            sender.PublishBinaryMessage("WindowsUri:WriteTag", message2.AsBuffer(), (se,r)=>
            {
                se.StopPublishingMessage(r);
            });
        });              
}

EDIT:

I have just checked with two devices, and in fact, it is possible to write-read more than once without separating and tapping the phones again. See the example below, where one device sends 5 messages and the other receives all of them:

Device 1 (sender):

ProximityDevice device = ProximityDevice.GetDefault();

device.DeviceArrived += (e) =>
    {
        for (int i = 1; i <= 5; i++)
        {
            e.PublishMessage("Windows.mySubType", "message " + i.ToString(), (s, m) =>
                {
                    s.StopPublishingMessage(m);
                });
        }
    };

Device 2 (receiver):

ProximityDevice device = ProximityDevice.GetDefault();

device.SubscribeForMessage("Windows.mySubType", (s, e) =>
    {
        Dispatcher.BeginInvoke(() =>
            {
                MessageBox.Show(e.DataAsString);
            });
    });
