Need help with NFC card emulation hardware project

Hey guys,

I am trying to setup a system where I can put together a simple hardware rig that supports NFC type A or B tag emulation. Doesn’t really matter what the hardware is. Many of the bits that I’m finding are easy to configure, but I need something that I can use to easily write code using libnfc or similar and have the device simply act like a tag emitting a URL (i.e. http://www.cnn.com).

Has anyone built a rig that does this? I have an ACR122U sitting around and I can do it with this, but that is not specifically what I want to use for this solution.
