Alien Registration Card for fingerprint?

[fhj1]

Friends,
I just got the fingerprint notice for naturalization process. The notice says that for applicanet of naturalization, I will need to bring the " alien registration card". Do you know what it is? Does the greencard count? I would appreciate it if you could help me out.
