You can simply push a NDEF message which contains one Ndef-Record of
type image/png or image/jpeg. Beyond memory (and time) there seem to
be no restrictions regarding the size of the message.
I just transferred an image of size 51K. Android delivered the 51166
byte message in 206 packages of size
Yes, I understand it varies by culture. Here (US), it's exacerbated by a lot

Note that using HTTPS does not give you end-to-end security in this
scenario. The server is a man-in-the-middle. It's not a surreptitious one,
but it is a man-in-the-middle nonetheless. The cert only serves to ensure
it's the *right* man in the middle.

Don't worry about the terminology -- "ad hoc wifi network" is what you're
looking for. I just wanted to figure out what you intended to say.
Hmm, "peer-to-peer" and "sensitive financial data" has me a bit concerned.
I don't advocate sending sensitive data, via servers or not, unencrypted. I

I thought I've read somewhere that the sticker would communicate with
the phone via Bluetooth. I guess that cannot be right as it would
need a power source.

Most probably not. A sticker is just an NFC chip that you can glue to

By peer-to-peer WIFI I meant that there is no router. I am no
networking expert (as you can tell), so my terminology is probably
off.
An intermediary server in my case is not an option due to the
sensitive nature of my custumers' financial data, so it needs to be

Android does support peer-to-peer wifi network, what exactly are you talking
about? I suspect you mean something somewhat different. Ad hoc access
points? You wouldn't want to do that anyway -- it would kill the user's
active WiFi connection, and this isn't even remotely a legitimate
applicatio
So are you saying the NFC would not be good for a Bump-type comm
between two devices? It just seems so much easier than pairing two
Bluetooth devices and since Android doesn't even support peer-to-peert
WIFI networking, that's completely out of the question.

Anyway, that's the standard. Then you need to consider what the library you
use is doing. If you're talking about the Android side, it looks like it
does the chunking for you:

Send? Just what do you think NFC is, exactly? It sounds like you think it's
an alternative to WiFi or Bluetooth. That's not exactly true, or only
approximately true, depending on how you want to look at it.
While in theory you could use it to communicate between two devices, the

I do not think I explained myself well.
What I need is the code, so that when i take a photo with my mobile.
it bring me the option to send the picture by nfc.

Hi,
As far as I know, I don't think you can put an image into a tag in a
standard way.
Check with Smart Poster Ndef tag type, maybe you can with this type.
If only your application need to read and write the image, you can
simply use Ndef type "Text" and put your image in a raw buffer.
Regards.
