What does it mean FP CODE 1,2,3?

[SL1977]

Does anybody know how many times we need to take finger printing? What is the meaning of CODE 1, 2, 3 for FP? Do i have to take another FP after CODE 3 then, CODE 2 and CODE 1?

How long i have to wait to get GC after giving FP CODE 3?

Please advice....Thank you,
