Talking to a poster with your phone

I am teaching Symbian on our MSc course since last Monday so not had much time for blogging or unhappily the smart phone show this year. However, I came across the article discussing the recent development from the NFC forum defining a specification for smart posters which interested me. In other words a specification for posters containing passive RFID tags whereby users could download music, videos, or the like. Interestingly the article suggested that it was more of interest for driving date traffic through embedded urls but I’m not convinced by that. Another part of the article poses the question as to when we are likely to see this on a more feature rich handset which is something I would also like to know if anyone has an answer.

SimonWhilst I would acknowledge that these phones are relatively rare in the west now if you look at Japan NttDoCoMo has shipped 5.5 million such devices and Sony announced that all new laptops will be NFC enabled it would only seem a matter of time. Having done trials with 2D barcodes compared directly to NFC I found that NFC had the following advantages :
(i) faster read times, as the tags can be accessed at rates between in excess of 100 kbits/s, whereas the two dimensional barcodes require Image capture and processing which we found typically takes a few seconds
(ii) RFID tags are more flexible as they can be written to as well as read from
(iii) simpler reading method, as the phone and the tag have merely to touch or be placed in close proximity (less than 3cm) whereas the barcodes require the user to take a picture. In fact, the phone and RFID tags used in this project provide round target icons to make positioning intuitive.
(iv) more robust, as errors are more likely to occur when scanning a barcode due to irregular camera orientation.

I am interested in doing some work for a university project in RFID using the Nokia 5410i phone and NFC reader.
I've posted this link http://discussion.forum.nokia.com/forum/showthread.php?t=96038&highlight=rfid to see if there is any alternative to developing Java Midlets for the phone without using the Nokia NFC & RFID SDK (Toolbox v. 2.0). Do you know if this is at all possible, as the is not a chance in hell of me being able to afford the 2000 Euro price tag. Do you know if the SDK is available for academic use at a cheaper price, or free?
If not is there still a way of coding for the NFC shell? Any help would be appreciated, as I need this clarified before purchasing the phone and reader. Otherwise it looks like I will have to buy a PDA with a RFID CF Reader, and learn .NET for Windows Mobile. :(
Many Thanks

However, rfid phones are rare for now.
I came accross an alternative solution : 2d barcodes, which contains lots of error correction and redundant informations, and are therefore quite easy to read, via the phone camera. And way easier to include in a phone.
