הבנק ישלח כרטיס חלופי בתנאי שבעל הכרטיס ישלים את האימות.

Because the sentence describes something that will happen later: the bank will send a replacement card.
In Hebrew, ישלח is the 3rd person masculine singular future form of לשלוח (to send).

• הבנק = the bank
• ישלח = will send

Hebrew verbs usually agree with the subject in person, number, and sometimes gender, and הבנק is grammatically masculine singular.

In Hebrew, nouns have grammatical gender. בנק is a masculine noun, so the verb agrees with it in the masculine singular form:

• הבנק ישלח = the bank will send

Even though bank is not a male person, Hebrew still assigns it grammatical gender.

Because it means a replacement card, not the replacement card.

• כרטיס חלופי = a replacement card
• הכרטיס החלופי = the replacement card

Hebrew often leaves a noun indefinite when English would use a/an. There is no separate Hebrew word for a.

בתנאי ש־ means on condition that or more naturally provided that / as long as.

So:

• בתנאי ש־בעל הכרטיס ישלים את האימות
  = provided that the cardholder completes the verification

It introduces a condition. It is a bit more formal than simple אם (if).

Yes, but the nuance changes a little.

• אם בעל הכרטיס ישלים את האימות... = if the cardholder completes the verification...
• בתנאי שבעל הכרטיס ישלים את האימות... = provided that / on condition that the cardholder completes the verification

בתנאי ש־ sounds more like a stated requirement or policy condition, which fits a bank-related sentence very well.

Literally, it means owner of the card or holder of the card.

This is a construct phrase in Hebrew:

• בעל = owner / holder
• הכרטיס = the card

Together, בעל הכרטיס means the cardholder.

This is very common in Hebrew. Instead of using a separate word like English cardholder, Hebrew often builds a phrase like X of the Y.

Because Hebrew usually prefers the construct state for this kind of relationship.

• בעל הכרטיס = the normal, natural way to say the cardholder / owner of the card
• הבעל של הכרטיס would sound odd here, and בעל can also mean husband, so it may even be confusing

In formal and standard Hebrew, בעל הכרטיס is the correct and natural phrasing.

Because after בתנאי ש־, Hebrew commonly uses the future tense to describe a condition that may happen later.

• ישלים = will complete

So the idea is:

• The bank will send a replacement card
• provided that the cardholder completes / will complete the verification

In English, we often say if the cardholder completes, not will complete, but Hebrew regularly uses the future here.

ישלים comes from the root ש־ל־ם. In this verb pattern, להשלים means to complete.

So:

• להשלים = to complete
• ישלים = he will complete

Do not confuse this with other words from the same root, such as:

• שלום = peace / hello
• שלם = whole / complete / paid

Hebrew roots often produce several related meanings.

Because האימות is a definite direct object.

In Hebrew, את is used before a direct object when that object is definite, usually marked by ה־ (the).

• ישלים את האימות = will complete the verification

Compare:

• ישלים אימות = will complete a verification
• ישלים את האימות = will complete the verification

So את does not mean a separate word like to or with here; it is a grammatical marker.

האימות means the verification.

It comes from אימות, which is a noun meaning verification, validation, or authentication, depending on context.

In a banking context, האימות usually refers to an identity or security verification process.

Both are possible in different contexts, but they are not exactly the same.

• להשלים את האימות = to complete the verification process
• לאמת = to verify / authenticate

The sentence focuses on finishing a required process, so ישלים את האימות is very natural: the cardholder must complete the verification.

The sentence is:

• הבנק ישלח כרטיס חלופי בתנאי שבעל הכרטיס ישלים את האימות.

Its basic structure is:

• Subject: הבנק
• Verb: ישלח
• Object: כרטיס חלופי
• Condition phrase: בתנאי ש...

So literally:

• The bank will send a replacement card, provided that the cardholder completes the verification.

This word order is very natural in modern Hebrew.

A simple pronunciation guide is:

ha-bank yishlaḥ kartis ḥalufi, bitnai she-ba'al ha-kartis yashlim et ha-imut

A few notes:

• ḥ represents the Hebrew letter ח, a throaty sound not found in standard English
• ba'al has a slight break between the vowels
• et is pronounced like et, but it is usually unstressed

It sounds neutral to formal, which fits official messages from a bank.

Words and phrases like:

• בתנאי ש־
• כרטיס חלופי
• ישלים את האימות

are very typical of customer service, legal, administrative, or banking Hebrew. In everyday casual speech, people might simplify some parts, but this sentence is completely natural in formal written Hebrew.
