هو يسجل الدخول ببطاقة الموظف.

Yes. In Arabic, يسجل already tells you the subject is he because the verb is marked for third person masculine singular. So:

• يسجل الدخول ببطاقة الموظف = He logs in / is logging in with the employee card
• هو يسجل الدخول ببطاقة الموظف means the same basic thing, but هو adds emphasis or clarity.

Arabic often includes a subject pronoun when the speaker wants to be explicit, contrastive, or simply stylistically clear.

يسجل is the imperfect verb form. In Modern Standard Arabic, this form can cover:

• he logs in
• he is logging in
• he logs in regularly

The exact English tense depends on context. Arabic does not always separate simple present and present progressive the way English does.

The dictionary form is سجّلَ.

This is a Form II verb, built from the root س-ج-ل, which is connected with recording, registering, or entering information.

So:

• سجّلَ = he registered / recorded
• يسجّلُ = he registers / is registering

In this sentence, يسجل الدخول is a common expression meaning to log in or to sign in.

Arabic often expresses ideas like log in, enter, sign in, or register entry with a verb + verbal noun combination.

Here:

• يسجل = he registers
• الدخول = the entering / entry

Together, يسجل الدخول literally means something like he registers the entry, but idiomatically it means he logs in or signs in.

This kind of structure is very common in Arabic.

Because Arabic often uses the definite verbal noun in fixed expressions like this.

• الدخول literally = the entering / the entry

In expressions such as:

• سجل الدخول = log in
• سجل الخروج = log out / sign out

the noun is commonly definite. It functions almost like part of a set phrase rather than a separately translated the in natural English.

الدخول is a verbal noun (also called a maṣdar). It comes from the verb دخل = to enter.

So grammatically, this sentence has:

• يسجل = the main verb
• الدخول = a verbal noun acting as the object of that action

This is similar to English structures like make an entry, perform a login, or record the entry, though the natural translation is simply log in.

Here بـ means with or by means of.

So:

• ببطاقة الموظف = with the employee card / using the employee card

This بـ is very common for expressing the instrument or means used to do something:

• بالقلم = with a pen
• بالهاتف = by phone / using the phone
• بالبطاقة = with the card

The preposition بـ is attached directly to the following word in writing.

So:

• بـ + بطاقة = ببطاقة

This is normal Arabic spelling. Many short prepositions attach to the next word, such as:

• بِ = with/by
• لِ = for/to
• كَ = like/as

بطاقة الموظف is an iḍāfa construction, often called a construct phrase. It means:

• بطاقة = card
• الموظف = the employee

Together:

• بطاقة الموظف = the employee’s card / employee card

In an iḍāfa:

1. the first noun usually does not take الـ
2. the second noun determines definiteness

Because الموظف is definite, the whole phrase بطاقة الموظف is definite.

Because in an iḍāfa construction, the second noun is put in the genitive case.

So grammatically:

• بطاقةُ الموظفِ in full case endings

In normal everyday writing, short vowels are usually omitted, so you just see بطاقة الموظف. But the relationship is still there: card of the employee.

Most literally, it means the employee’s card because الموظف is definite.

Depending on context, English may also naturally say employee card. Arabic iḍāfa phrases often have to be translated flexibly into English:

• بطاقة الموظف = the employee’s card / employee ID card / employee card

The best English version depends on the situation.

Yes, but the meaning or emphasis may shift.

The given sentence is:

• هو يسجل الدخول ببطاقة الموظف

This is a normal, clear order. Arabic could also say:

• يسجل هو الدخول ببطاقة الموظف
• ببطاقة الموظف يسجل الدخول

These alternatives are more marked and usually change emphasis. For learners, the original order is the safest and most natural to use.

It could be either.

Because يسجل is in the imperfect, the sentence can mean:

• He logs in with the employee card (habitual / general)
• He is logging in with the employee card (right now)

Context decides which is meant. If Arabic wants to make right now clearer, it might add a time word such as:

• الآن = now

So:

• هو يسجل الدخول الآن ببطاقة الموظف = He is logging in now with the employee card

A careful pronunciation would be roughly:

• huwa yusajjilu ad-dukhūla bibiṭāqati al-muwaẓẓaf

A few helpful notes:

• يسجل has a doubled j sound because of the shadda: yusajjil
• الدخول begins with ال, but after pronunciation rules it sounds like ad-dukhūl because د is a sun letter
• ببطاقة may sound like bibiṭāqa... because the preposition bi- comes before biṭāqa

In ordinary pause pronunciation, many final short vowels are not pronounced fully.
