After few weeks of using the phone, yesterday I tried to use NFC to send photos to Galaxy SIII, and the phone asked to enable Bluetooth? If need to enable Bluetooth first, what's the point of using NFC to transfer photos? And yesterday it failed, the Galaxy SIII can only detect but nothing happened. Haven't tried it on other Lumia 920 yet.
So, I sent the photos using Bluetooth to the SIII and it worked. Very quickly and convenient.

As I understand it S3 uses wifi direct after its made a NFC connection and L920 uses Bluetooth after NFC e.g the NFC just helps pair the two phones to send the data over another technology as NFC transfers are quite slow. It is abit annoying you cant send from wp8 to droid via nfc as they use different tech but maybe one day they will support each others systems

Gonna try it on other Lumia 920 to see whether it works just like the advertisement.
When the rooms are empty or not crowded, it's actually easier to send using Bluetooth. Beside, it can find the SIII and connected to it using Bluetooth pretty fast.

Hope Nokia will improve the NFC tap and send function on WP8, so it'll be just really tap and send to share file(s).

I wonder if the payment method using NFC, is it using Wifi Direct or Bluetooth. Or perhaps, the counter will ask. "How would like to pay your bill, Sir/Ma'am? By Bluetooth or Wifi Direct."
In current method, it's not Tap+Send, but Tap+Tap+Tap+Tap+Send.

Windows Phone 8 support both Bluetooth and WiFi tor tap+send feature although the wifi part is not wi-fi direct (Android only feature) and requires two phones connected to the same wifi network. But wifi does work and transfers files much faster than Bluetooth.

Let's say on average, the picture taken using the camera will have around 2.5 MB of size.
The supported NFC speeds, 424 kbit/s (theoretical), so in real life, let's say we take 1/3 of it, so = 141.33 kbit/s
Time taken = (2.5 MB*1024 kB*8 bits) / 141.33 kbit/s
= 144.9 seconds
= 2.4 minutes.

NFC is a set of defined message types. So to send a large files, you will need to encode and embed the files into a message body. So, it does not come out as simple as you suggested. It's more like try to send a picture through SMS without using the MMS (and use cellular data) feature. Doable but not what anyone wanted and it is not standardized either.

From reading this, I think you're missing the point. The files do transfer via Bluetooth, but use NFC to pair the phones to enable Bluetooth transfer. Take NFC out of the equation and you have to the pairing process manually, which is more time consuming even in the most convenient circumstances.
NFC tap, phones paired, transfer via Bluetooth
Set phones to discover other devices by Bluetooth on both phones, wait for discovery, ask for the Bluetooth password for both phones, enter password, wait for connection, transfer via Bluetooth.

I did between an L920 and 8x and it works alas not as smooth as the commercial suggests. It takes quite a few seconds through BlueTooth. A little bit faster on WiFi. But definitely not as fast as you would thought. Try those Samsung GS3 commercials. Tap the phone to transfer a video while a taxi is driving away. That's pure fanctasy land.
