NFC on Nexus S

Hello experts,

I have nexus s mobile with me. I am working with the smartcard apps on android. As i surfing over net, I came to know that nexus s mobile is able to read the smartcard tags. When i tried to connect my smartcards with nexus s , I am unable to get the tag information and i have no Response. why is that not connected with nexus s . All i need to know is, Is there any specific needs for smartcards that should satisfy to connect with nexus s ?? Or what kind of tags we can connect with nexus s mobile.

Can anyone pls give me your valuable suggestion.

Thanks,
Dilip.

Do you have the GSM version of the Nexus S or the US version (it is the same name just with 4G in the name)? Because the GSM version does not have a NFC in it according to Android Central.


Hope this helps you.

(I would post links to the two specs but apparently this forum wont let me unless i get 15 points :? )
