The meaning of "agile" and "associate"

[Hanka]

Hello,

could you please tell me in which sense is the word "agile" used in this phrase:

AGILE REFERENCE NUMBER

And one more thing:

A text concerning a computer utility includes a phrase:

ASSOCIATES REQURED

Does the word "associates" refer to some partners or persons or could it also mean an associated computer program?

Thank you very much

Agile makes no sense to me unless it is some sort of acronym. For 'associates', I'd tyhink of them as partners here.
