✦Grammar Breakdown
BitteüberprüfedeineKartendaten.
Bitte + Imperativ
Placing "Bitte" before an imperative makes the request polite and less forceful.
Imperativ du (überprüfen)
For verbs ending in -en, the du‑imperative is formed with the stem + "e" (optional). Here: "überprüfe".
Possessive Determiner (deine)
"deine" is the accusative plural form of "dein" and matches the plural noun "Kartendaten".
Compound Noun (Kartendaten)
"Kartendaten" combines "Karte" (card) and "Daten" (data) and is plural, taking the accusative case after the verb.

Okay, I'll look at them right away.
✕Common Mistakes
Bitte überprüfen deine Kartendaten.
Using the infinitive instead of the imperative makes the sentence sound like a statement, not a request.
Bitte überprüfe dein Kartendaten.
The possessive must agree with the plural noun "Kartendaten"; "dein" is singular.
Bitte überprüfe deine Kartendaten
Omitting the final period is fine in speech, but in written German the sentence should end with a period or exclamation mark.
Bitte überprüfe Sie Ihre Kartendaten.
Mixing the informal "Bitte" with the formal "Sie" is inconsistent; choose one register.
↔Alternatives

Schau bitte nach deinen Kartendaten.
Please take a look at your card details.
Cultural Tip
In German, the combination of "Bitte" with an informal du‑imperative is friendly yet respectful, perfect for apps that address the user personally. If you need a formal tone (e.g., in business correspondence), switch to the Sie‑form: "Bitte überprüfen Sie Ihre Kartendaten."
