Help with sending data through SCL3711 to Galaxy Nexus in win 7

Hi
So I am new to NFC and am attempting to use it for a school project. Basically, our idea is to send receipts from windows-based POS systems to android phones via NFC. We aren't very sure of how to approach this. Is it possible to to this by setting up the SCL3711 as a target, or would I have to use LLCP/SNEP or some other protocol to to this?

One thing is that we are using libnfc 1.5.1 through C# so as to intergrate it with the rest of the application, since we are programming for windows. This restricted us from using libnfc-llcp. Also currently, using  nfc_target_init() fails every time, even using the examples given.

Any help would be greatly appreciated!

Edit:
Just to add on, using a few examples such as nfc-emulate-forum-tag4.exe (LibNFC 1.6.0) results in:

NFC device: SCM Micro / SCL3711-NFC&RW - PN533 v2.7 (0x07) opened
