Either would be correct in this context.

Generally, the present perfect simple tense describes what has been happened so far, while the present perfect continuous suggests that something is ongoing or unfinished. The distinction isn't strong enough in this question to make a big difference.

Looking at two possible responses to the question might highlight the differences better.

(present perfect simple) I've worked here five years and I've loved every moment of it!

(present perfect continuous) I've been working here five years, but it's only recently that I was transferred to this office.

Similarly, one could say:

(present perfect simple) He's worked three hours today [he might work more, or he might go home after this].

(present perfect continuous) He's been working the whole morning [and he's still not done with his work].

Either can be used, but it depends on context.

The first would be used in describing the process of being caught speeding. "If a policeman has pulled you over for speeding, once your ID card number has been noted, etc." In this case, the situation is described as having occurred at some time in the past, so the "has been noted" is the proper tense.

The second would be used as part of a narrative. "Imagine you're driving down the highway, not paying attention to the speedometer. A police officer pulls you over and issues you a ticket, and takes your ID card back to his cruiser. Once your ID card number is noted, there's no way of escaping the fine." Here, the situation is described in present (what you might call hypothetical or imaginary) tense, so "is noted" is appropriate.
