Ok, so i need a relay.

This is what im using

What relay would you suggest getting?  Obviously a 12V one but i've never messed with one before.  Any help?

"and let the 12V be applied across the strike lock,"

I think this is what i do not know how to do.

I'm very new with working with electronics like this and need some advice.  

I'm trying to build and RFID door lock(yeah i know..very original) that triggers a 12V electric strike lock.  How  do i provide this power?  As much description as possible would rule.  I'm a noob with the hardware/physical side of this.
