Контактний центр може розблокувати платіжну картку.

Because Ukrainian often uses a modal verb + infinitive pattern, just like English.

• може = can / is able to
• розблокувати = to unblock / to unlock

So:

• Контактний центр може розблокувати платіжну картку.
• literally: The contact center can unblock the payment card.

This works very much like English can unlock.

може is the 3rd person singular present-tense form of могти (to be able to / can).

Here are a few forms:

• я можу = I can
• ти можеш = you can
• він / вона / воно може = he / she / it can
• ми можемо = we can
• ви можете = you can
• вони можуть = they can

Since контактний центр is singular, you use може.

розблокувати is the infinitive, meaning to unblock / to unlock.

After може, Ukrainian normally uses the infinitive:

• може розблокувати = can unblock
• може допомогти = can help
• може пояснити = can explain

Also, розблокувати is a perfective verb. That means it focuses on completing the action: to get the card unblocked.

Its imperfective partner is usually розблоковувати, which would be used when talking about process, repetition, or general activity.

Because it is the direct object of the verb, so it goes into the accusative case.

The base form is:

• платіжна картка = payment card

But after a transitive verb like розблокувати, the direct object changes to accusative:

• платіжну картку

Both words are feminine singular, so both change:

• платіжна → платіжну
• картка → картку

This is a very common pattern for feminine nouns and adjectives.

The endings show it:

• adjective: -у / -ю is a common feminine singular accusative ending
• noun: -у / -ю is also common for feminine singular accusative nouns ending in -а / -я in the nominative

So:

• nominative: платіжна картка
• accusative: платіжну картку

Compare:

• Я бачу нову машину. = I see a new car.
• Вона читає цікаву книжку. = She is reading an interesting book.

Same kind of change.

Платіжна картка means payment card. In real life, it usually refers to a card used for payments, such as a debit or credit card.

A few related expressions:

• платіжна картка = payment card
• банківська картка = bank card
• кредитна картка = credit card
• дебетова картка = debit card

In many contexts, платіжна картка and банківська картка can overlap, but платіжна картка is a bit more formal and precise.

Both forms exist, but they are used a bit differently.

• контактний центр is a fully Ukrainian-style phrase: contact center
• контакт-центр is also common and closer to the international compound style

In official or formal Ukrainian, you may often see контактний центр. In business language, контакт-центр is also very normal.

So this sentence uses a natural, standard Ukrainian phrasing.

It is in the nominative case, because it is the subject of the sentence.

Base form:

• контактний центр

Why nominative?

Because it is the thing doing the action:

• Контактний центр може розблокувати...
• The contact center can unblock...

The adjective контактний agrees with центр:

• центр is masculine singular
• so the adjective is also masculine singular nominative: контактний

Yes. Ukrainian word order is more flexible than English, though the neutral order here is very natural:

• Контактний центр може розблокувати платіжну картку.

You could also say:

• Платіжну картку може розблокувати контактний центр.

This puts more emphasis on the payment card or on who is able to unblock it.

In Ukrainian, changing word order often changes focus or emphasis, not the core meaning.

No. Ukrainian has no articles like English a / an / the.

So:

• платіжну картку can mean a payment card or the payment card

The exact meaning depends on context.

In this sentence, English might translate it as either:

• The contact center can unblock a payment card
• The contact center can unblock the payment card

Usually the wider situation tells you which one is meant.

A practical pronunciation guide with stressed syllables:

• конта́ктний це́нтр мо́же розблокува́ти платі́жну ка́ртку

Rough English-style approximation:

• kon-TAKT-nyi TSENTR MO-zhe roz-blo-ku-VA-ty pla-TEEZH-nu KART-ku

A few notes:

• г in Ukrainian is usually not a hard English g
• и is not the same as English ee
• картку has a clear k sound before u
• stress matters, but Ukrainian stress must often just be learned word by word

Yes, but that means the opposite.

• розблокувати = to unblock / unlock
• заблокувати = to block

So:

• Контактний центр може розблокувати платіжну картку. = The contact center can unblock the payment card.

• Контактний центр може заблокувати платіжну картку. = The contact center can block the payment card.

The prefix роз- often adds the idea of reversing or undoing something here.
