Nhân viên quét thẻ căn cước.

• nhân viên = employee, staff member
• quét = to scan, sweep, or swipe, depending on context
• thẻ căn cước = ID card / identity card

So the sentence structure is:

• Nhân viên = subject
• quét = verb
• thẻ căn cước = object

A natural English translation is The employee scans the ID card or An employee scans the ID card.

Vietnamese usually does not require articles like the, a, or an.

So nhân viên can mean:

• the employee
• an employee
• sometimes just employee/staff

And thẻ căn cước can mean:

• the ID card
• an ID card

The exact meaning depends on context. This is very normal in Vietnamese.

Yes. This sentence uses the basic Vietnamese word order:

• Subject + Verb + Object

So:

• Nhân viên = subject
• quét = verb
• thẻ căn cước = object

That makes it quite straightforward for English speakers.

Yes. Quét has a few related meanings, including:

• to sweep
• to scan
• to swipe

In a sentence with a card, quét usually means something like:

• scan the card
• swipe the card

So quét thẻ căn cước suggests using the ID card with a scanner, reader, or checking device.

Yes. In real life, the best English translation depends on the situation.

• If a machine reads the card electronically, scan is natural.
• If the card is passed across a reader, swipe may be more natural.

Vietnamese quét can cover both ideas in this kind of context.

Thẻ căn cước means an identity card or ID card.

In modern Vietnamese, you may also see:

• căn cước công dân = citizen ID card
• thẻ căn cước công dân = citizen identity card

In everyday use, people may shorten things depending on context. So thẻ căn cước is understandable as ID card.

Thẻ means card. Adding thẻ makes it clear that you are talking about the physical card itself.

Compare:

• căn cước = identity / ID status, or shorthand for identity card in some contexts
• thẻ căn cước = the actual ID card

So in a sentence about scanning, thẻ is very natural because a machine scans the card.

By itself, nhân viên can be singular or plural. Vietnamese nouns usually do not change form for number.

So depending on context, it could mean:

• the employee
• an employee
• employees

However, in this short sentence, most learners will naturally read it as singular: The employee scans the ID card.

If you want to make plurality clearer, Vietnamese can add words like:

• các nhân viên = the employees
• một nhân viên = one employee / an employee

Vietnamese verbs do not change form for tense the way English verbs do. Quét itself does not mean specifically present, past, or future.

So Nhân viên quét thẻ căn cước could mean, depending on context:

• the employee scans the ID card
• the employee scanned the ID card
• the employee will scan the ID card

If you want to make the time clearer, you can add markers such as:

• đang quét = is scanning
• đã quét = scanned / has scanned
• sẽ quét = will scan

Yes. It is grammatical and natural as a simple statement.

It sounds like:

• a description of an action
• a caption
• a procedural step
• part of a larger context

Because Vietnamese often leaves out information that is already understood, a short sentence like this is completely normal.

You can say:

Nhân viên đang quét thẻ căn cước.

Here:

• đang marks an action in progress

So:

• quét = scan
• đang quét = is scanning

You can add time markers:

• Nhân viên đã quét thẻ căn cước. = The employee scanned / has scanned the ID card.
• Nhân viên sẽ quét thẻ căn cước. = The employee will scan the ID card.

These extra words help specify time, since the verb itself does not change.

A rough guide is:

• nhân viên ≈ nyun vyeen
• quét ≈ kwet, with a rising tone
• thẻ ≈ te, with a falling-rising tone
• căn cước ≈ gun kuək, with the correct Vietnamese vowels and tones

The tones matter a lot in Vietnamese, so it is best to listen to native audio if possible. A learner should pay special attention to:

• nh
• qu
• the vowel combinations in cước
• the tones on quét, thẻ, and cước

Yes, if you want to be more specific.

For example:

• Nhân viên quét một thẻ căn cước. = The employee scans an ID card.
• Nhân viên quét chiếc thẻ căn cước. = The employee scans the ID card / that ID card.

But in many everyday sentences, Vietnamese does not need a classifier here. The shorter version is perfectly natural.

Sometimes people may understand it from context, but Nhân viên quét thẻ căn cước is clearer if you mean scanning the physical card.

Without thẻ, the phrase can sound less precise, because căn cước is not only the card itself but also the broader idea of identity/identification. If a machine is reading the card, including thẻ is a good choice.
