Anche quando la carta è valida, esibiamo la fototessera.

In this sentence, anche quando means even when.

It introduces a situation that does not change the main action:

• Anche quando la carta è valida, esibiamo la fototessera.
• Even in that case, the action still happens.

So the structure is:

• anche = even / also
• quando = when

Together, they often express a concessive idea: even when X is true, Y still happens.

Good question. Anche se usually means even if or although, while anche quando means even when.

The difference is subtle but important:

• anche quando points to a time or recurring situation
• anche se points more to a condition or contrast

Here, anche quando works well because the sentence is talking about a situation that can actually occur: whenever the card is valid, we still show the photo.

Very roughly:

• anche quando = even when that situation happens
• anche se = even if / although that is the case

In many contexts, both can sound possible, but anche quando emphasizes the recurring situation more naturally.

Carta can mean several things in Italian depending on context:

• paper
• card
• document
• pass

In this sentence, it most likely means some kind of card or document.

Italian often uses words like carta, documento, or tessera in ways that depend heavily on context, so the exact English word may vary.

Italian uses definite articles much more often than English does.

So where English might say:

• when the card is valid or sometimes just
• when your card is valid

Italian very naturally says:

• quando la carta è valida

This is normal Italian usage. The article does not necessarily mean a very specific card already mentioned; it can simply refer to the relevant card in context.

Because è is the verb essere in the third-person singular present: is.

The accent is important because it distinguishes it from e, which means and.

So:

• è = is
• e = and

This is one of the most important written distinctions in Italian.

Because valida agrees with la carta, which is a feminine singular noun.

In Italian, adjectives usually agree in gender and number with the noun they describe:

• il documento è valido
• la carta è valida

So:

• masculine singular: valido
• feminine singular: valida

Esibiamo is:

• present indicative
• first person plural
• from the verb esibire

So it means we present, we show, or we display.

The ending -iamo tells you the subject is we.

Because Italian often omits subject pronouns when they are not needed.

The verb ending already shows who the subject is:

• esibiamo = we show

So noi is optional.

You would add noi only for emphasis, contrast, or clarity:

• Noi esibiamo la fototessera, loro no.
• We show the photo, they don’t.

Without emphasis, leaving out noi is more natural.

Esibire is a bit more formal and often used when you present something for inspection, especially in official or procedural contexts.

So:

• mostrare = to show
• esibire = to present / to produce / to show formally

In a sentence about documents, identification, or procedures, esibire sounds very natural.

Fototessera is a compound noun:

• foto = photo
• tessera = card / pass / small document

In actual usage, fototessera usually means a passport-style ID photo, the small photo used for documents.

So it does not normally mean a full identity card by itself. It refers to the small official-style photograph.

For the same general reason as la carta: Italian usually includes the article with concrete nouns when referring to a known or relevant item.

So esibiamo la fototessera is the natural way to say that we present the photo required in that context.

English sometimes omits or changes the article depending on style, but Italian normally keeps it.

Because the sentence begins with a subordinate clause:

• Anche quando la carta è valida, ...

Then comes the main clause:

• esibiamo la fototessera

In Italian, when a subordinate clause comes first, a comma is very common and natural. It helps separate the two parts clearly.

Yes. You could also say:

Esibiamo la fototessera anche quando la carta è valida.

This keeps the same basic meaning.

The difference is mainly one of emphasis:

• Anche quando la carta è valida, esibiamo la fototessera.
  Focuses first on the situation.
• Esibiamo la fototessera anche quando la carta è valida.
  Focuses first on the action.

Both are grammatical.

Usually it sounds like a general rule or habitual action, because the Italian present tense often covers that meaning.

So esibiamo here is probably not just we are showing right now, but more like:

• we show
• we present
• we do this as a rule

Italian present tense is often used for procedures, instructions, habits, and general truths.
