purple finger

[robuca]

Hello...
1) I have some questions about the "purple finger" which I can figure out but, in which stage of the voting process you must get yourself purple fingered?

2) what's the name of the "tool", I mean a slip of paper with all the infos about the running candidate gives away to voters who intend to cast their ballot on them... what is the exact word for this election prop... Thanks a lot in advance! Rodrigo (Brazil)

Please provide your source context.

Presumably it will be after you have voted, to indicate that you have already voted and thus are not eligible to vote again.
