Because 출입 카드 is the direct object of the verb 받았어요 (received).

• 출입 카드 = access card / entry card
• 를 = object particle
• 출입 카드를 = the access card as the thing being received

In Korean, the thing you receive takes 을/를.

에게 marks the person from whom something is received.

So:

• 직원에게 = from the staff member / from an employee

With 받다 (to receive), Korean often marks the source person with:

• 에게 (common, standard)
• 한테 (more casual)
• sometimes 께 (honorific, for someone deserving respect)

So this sentence literally works like:

• I received the access card from the staff member.

Korean chooses the verb based on the speaker’s perspective.

• 받다 = to receive
• 주다 = to give

If the speaker is saying I got the card from the staff member, then 받다 is natural.

So:

• 출입 카드를 직원에게 받았어요 = I received the access card from the staff member.

If you wanted to say The staff member gave me the access card, you would use 주다 instead, for example:

• 직원이 저에게 출입 카드를 줬어요.

Same situation, different viewpoint.

받았어요 is:

• past tense
• polite informal style (often called 해요체)

Breakdown:

• 받다 = dictionary form
• 받았어요 = received / got

This style is very common in everyday polite conversation.

Compare:

• 받아요 = receive / am receiving
• 받았어요 = received
• 받았습니다 = received (more formal)
• 받았어 = received (casual)

The subject is omitted, which is very common in Korean.

From context, it usually means something like:

• I received the access card from the staff member.

But depending on context, it could also mean:

• he/she/they received the access card from the staff member

Korean often leaves out subjects when they are already understood.

If you wanted to include it, you could say:

• 저는 출입 카드를 직원에게 받았어요. = I received the access card from the staff member.

Both are possible.

Korean word order is flexible, especially for phrases marked clearly by particles like 를 and 에게.

So these are both natural:

• 출입 카드를 직원에게 받았어요
• 직원에게 출입 카드를 받았어요

The verb usually comes at the end, but before the verb, Korean can move phrases around for emphasis, flow, or context.

Very roughly:

• 출입 카드를 직원에게 받았어요 may slightly foreground the access card
• 직원에게 출입 카드를 받았어요 may slightly foreground the staff member as the source

But in many situations, the difference is small.

Yes. In everyday speech, 한테 is very common.

So you could say:

• 출입 카드를 직원한테 받았어요.

This means the same thing: I received the access card from the staff member.

General feel:

• 에게 = standard, neutral
• 한테 = more conversational
• 께 = honorific

For example:

• 선생님께 받았어요 = I received it from the teacher (respectful)

출입 means entering and leaving / access, and 카드 means card.

So 출입 카드 is an access card, entry card, or key card, depending on context.

It is often used for cards that let you enter:

• office buildings
• restricted areas
• dorms
• company rooms
• apartment entrances

So the exact English translation can vary a little, but the Korean phrase is straightforwardly about a card for access.

Yes. In Korean, particles often carry meanings that English expresses with separate prepositions.

Here, 에게 does the job of to/from a person, depending on the verb.

With 주다 (to give), 에게 often means to:

• 직원에게 줬어요 = gave it to the staff member

With 받다 (to receive), 에게 is understood as from:

• 직원에게 받았어요 = received it from the staff member

So the verb determines how that relationship is understood.

Usually, for receiving something from a person, 에게/한테 is the normal choice.

• 직원에게 받았어요 = natural

Using 에서 with a person here would usually sound unnatural to learners at this level.

에서 is more commonly used for:

• location of an action
• source from places/organizations in some contexts

For a person giving you something, stick with:

• 에게
• 한테
• 께 (honorific)

A more formal version would be:

• 출입 카드를 직원에게 받았습니다.

This uses 받았습니다, which is the formal polite style.

Comparison:

• 받았어요 = polite, everyday
• 받았습니다 = more formal, often used in workplaces, announcements, reports, or customer service

By itself, 직원 can mean staff member / employee, and Korean often does not mark singular vs. plural unless necessary.

So 직원에게 most naturally means:

• from the staff member
• or from a member of staff

If you really wanted to make it plural, you might say:

• 직원들에게 = from the staff members

But in many real situations, Korean leaves that unspecified.

In careful romanization, it is roughly:

• churip kadeureul jigwon-ege badasseoyo

But natural pronunciation changes a bit because Korean sounds link together.

A learner may hear something closer to:

• 출입 카드를 → 추립 카드를
• 받았어요 → roughly 바다써요

You do not need to force English-like word boundaries. In Korean, sounds flow together smoothly.

A good learner goal is to recognize these chunks:

• 출입 카드를
• 직원에게
• 받았어요

That will help both listening and speaking.
