Μετά την ταυτοποίηση στοιχείων, χρεώστε έναν λογαριασμό· πιστώστε άλλον.

Here Μετά means after.

When μετά means after, it is followed by the accusative case in Modern Greek. That is why you get:

• μετά
• την ταυτοποίηση = the identification / verification

So:

• Μετά την ταυτοποίηση = After the identification / verification

This is a very common pattern:

• μετά το μάθημα = after the lesson
• μετά τη δουλειά = after work

Note that μετά can also mean with in some fixed or more formal uses when followed by the genitive, but in everyday Modern Greek, learners will most often meet μετά + accusative = after.

Because ταυτοποίηση is a feminine noun, and here it comes after μετά, which requires the accusative.

The basic forms are:

• nominative: η ταυτοποίηση
• accusative: την ταυτοποίηση

So in the sentence:

• Μετά την ταυτοποίηση...

the article changes to match the case.

Also, ταυτοποίηση here means something like:

• identification
• verification
• authentication

The exact English translation depends on context.

στοιχείων is the genitive plural of στοιχείο.

Main forms:

• singular: το στοιχείο
• plural: τα στοιχεία
• genitive plural: των στοιχείων

In this sentence, ταυτοποίηση στοιχείων means:

• verification of details
• identification of information
• verification of data

Greek often uses a noun + genitive structure where English would use of:

• ταυτοποίηση στοιχείων = verification of details/data
• άνοιγμα λογαριασμού = opening of an account
• έλεγχος εγγράφων = checking of documents

So στοιχείων is in the genitive because it depends on ταυτοποίηση.

In administrative, banking, or official language, στοιχεία often means:

• details
• information
• personal details
• data

It does not necessarily mean elements here, even though that is one literal meaning in other contexts.

So ταυτοποίηση στοιχείων is a standard formal phrase for something like:

• verification of details
• identity/data verification

If this is a banking or administrative instruction, that is the natural interpretation.

Both are imperative forms, meaning they give a command or instruction.

• χρεώστε = debit
• πιστώστε = credit

More specifically, these are the 2nd person plural imperative forms. In Greek, that form is used for:

• speaking to more than one person
• giving a polite/formal instruction to one person
• writing general procedural instructions, as in manuals or official directions

So this sentence sounds like a formal instruction, for example in a banking procedure.

It could be either, depending on context.

The 2nd person plural imperative in Greek can mean:

1. a command to more than one person
2. a polite command to one person
3. an instructional style used in manuals, forms, and official procedures

In a sentence like this, the most likely feeling is formal procedural instruction, not casual speech.

Compare:

• Χρέωσε τον λογαριασμό. = Debit the account.
  (singular, informal)

• Χρεώστε τον λογαριασμό. = Debit the account.
  (plural, polite, or formal/instructional)

Because Greek, like English, can leave the noun unstated when it is easy to understand from context.

So:

• χρεώστε έναν λογαριασμό = debit one account
• πιστώστε άλλον = credit another one

The second noun, λογαριασμό, is omitted because it is already understood.

This is very natural Greek.

The full version would be:

• χρεώστε έναν λογαριασμό, πιστώστε άλλον λογαριασμό

But repeating the noun is unnecessary.

Because άλλον has to agree with the missing noun λογαριασμό.

λογαριασμό is:

• masculine
• singular
• accusative

So the adjective/pronoun must match it:

• άλλον = another one
  (masculine singular accusative)

Compare:

• άλλος = another (mas. nom.)
• άλλον = another (mas. acc.)
• άλλη = another (fem.)
• άλλο = another (neut.)

Since the implied noun is λογαριασμό, άλλον is the correct form.

Because here άλλον means another one, not the other.

Greek often uses άλλος / άλλη / άλλο without an article in this meaning:

• Θέλω άλλο καφέ. = I want more / another coffee.
• Πάρε άλλο βιβλίο. = Take another book.
• πιστώστε άλλον = credit another one / another account

If you added an article, the meaning could shift depending on context, often toward the other rather than simply another.

λογαριασμός can mean several things in Greek, depending on context:

• account (especially bank account)
• bill
• calculation
• sometimes consideration in idiomatic uses

In this sentence, because of χρεώστε and πιστώστε, it clearly means a financial account.

So:

• έναν λογαριασμό = an account

The mark · is the Greek ano teleia, often translated as an upper dot.

It separates the two commands:

• χρεώστε έναν λογαριασμό
• πιστώστε άλλον

In English punctuation, it may feel similar to:

• a semicolon
• sometimes a colon
• sometimes a stronger pause than a comma

So the sentence is basically dividing two linked instructions:

• debit one account; credit another

It is very common in more formal or carefully written Greek.

Yes, the word order is natural and formal.

The structure is:

1. Μετά την ταυτοποίηση στοιχείων = introductory time phrase
2. χρεώστε έναν λογαριασμό
3. πιστώστε άλλον

This is a clear instruction sequence:

• first verify the details
• then debit one account
• then credit another

Greek word order is fairly flexible, but this order is very typical for formal instructions because it puts the condition or prior step first.

A slightly fuller version could be:

• Μετά την ταυτοποίηση των στοιχείων, χρεώστε έναν λογαριασμό και πιστώστε άλλον.

That would mean almost the same thing. The original is just more compact and procedural in style.

Yes, it is correct.

Greek often omits the article in this kind of formal noun phrase, especially in administrative, technical, or bureaucratic style.

So both of these are possible:

• ταυτοποίηση στοιχείων
• ταυτοποίηση των στοιχείων

The version without the article often sounds:

• more compact
• more official
• more like the language of instructions or forms

The version with the article can sound a little more specific: verification of the details.

So the sentence’s phrasing is very normal for formal written Greek.
