בתנאי שבעל הכרטיס ידווח, שירות הלקוחות יחסום את הכרטיס.

בתנאי ש־ introduces a condition and means something like provided that, on condition that, or as long as.

It is a bit stronger and more formal than אם, which usually just means if.

So:

• אם בעל הכרטיס ידווח... = If the cardholder reports...
• בתנאי שבעל הכרטיס ידווח... = Provided that the cardholder reports...

In this sentence, בתנאי ש־ emphasizes that blocking the card depends on that condition being met.

Because ש־ is a very common Hebrew prefix meaning that or introducing a subordinate clause, and it is usually attached directly to the following word.

So:

• בתנאי ש + בעל הכרטיס ידווח becomes
• בתנאי שבעל הכרטיס ידווח

This is completely normal Hebrew spelling. The ש־ is not a separate word here.

Hebrew often uses the future tense in both parts of a real future condition.

Here:

• ידווח = will report
• יחסום = will block

Even though English often says If the cardholder reports, customer service will block the card, Hebrew commonly uses future forms in both clauses when talking about a future possibility.

So this structure is very natural:

• בתנאי ש... ידווח, ... יחסום

Because its subject is בעל הכרטיס (the cardholder / owner of the card), which is grammatically singular masculine.

So the verb agrees with that subject:

• בעל הכרטיס ידווח = the male cardholder will report

If the subject were feminine, you would normally expect:

• בעלת הכרטיס תדווח = the female cardholder will report

Hebrew verbs in the future tense show person, number, and often gender.

Because שירות הלקוחות is grammatically singular.

Even though in English customer service may feel like a department or a group of people, in Hebrew שירות is a singular noun, so the verb is singular too:

• שירות הלקוחות יחסום = customer service will block

This is the same idea as in English when we say Customer service is handling it, not are handling it.

את marks a definite direct object.

In שירות הלקוחות יחסום את הכרטיס:

• שירות הלקוחות = the subject
• יחסום = the verb
• את הכרטיס = the definite direct object, the card

Hebrew uses את before a direct object when that object is definite, such as:

• with ה־: את הכרטיס
• with a name
• with a possessive, etc.

So:

• לחסום כרטיס = to block a card
• לחסום את הכרטיס = to block the card

Because the sentence mentions two different relationships involving the card:

1. בעל הכרטיס = the owner/cardholder of the card
2. יחסום את הכרטיס = will block the card

So the noun is repeated because it is part of two separate phrases. Hebrew often repeats nouns where English might also repeat them, especially when clarity is important.

Yes. Hebrew can also put the main clause first and the condition after it.

For example:

• שירות הלקוחות יחסום את הכרטיס בתנאי שבעל הכרטיס ידווח.

This means the same thing.

The version with the condition first:

• בתנאי שבעל הכרטיס ידווח, שירות הלקוחות יחסום את הכרטיס.

puts more focus on the condition. That word order is very natural, especially in formal or written language.

Yes, it is a very normal and understandable phrase. Literally it means owner of the card.

Depending on context, Hebrew may also use other expressions, but בעל הכרטיס is common and clear.

A useful point:

• בעל is masculine
• בעלת is feminine

So if you specifically wanted a female cardholder, you could say:

• בעלת הכרטיס

But in many contexts, especially formal ones, masculine wording may be used as a general default.

Yes, it sounds fairly formal or institutional.

Reasons:

• בתנאי ש־ is more formal than plain אם
• שירות הלקוחות sounds administrative/customer-service-like
• יחסום את הכרטיס is the kind of wording you might see in policies, banking instructions, or official notices

A more casual spoken sentence might choose simpler wording, but this sentence is perfectly natural in formal Hebrew.

The comma separates the introductory conditional clause from the main clause.

So the structure is:

• בתנאי שבעל הכרטיס ידווח = condition
• שירות הלקוחות יחסום את הכרטיס = main result

This is similar to English punctuation in sentences like:

• If the cardholder reports it, customer service will block the card.

The comma helps readability, especially when the condition comes first.
