On (impersonal pronoun)
‘On’ is used like ‘we/one’ in French and is common in spoken and written language for general statements.
a besoin de + noun
The verb ‘avoir besoin de’ requires a noun or infinitive after ‘de’; the preposition contracts with the article (d'une, du, de la).
d'une (contraction)
‘de’ + ‘une’ contracts to ‘d’une’; it signals a partitive or indefinite article.
pièce d'identité
A set phrase meaning ‘identity document’; usually a passport or national ID card.
ta vs votre
‘ta’ is informal (you, singular); in formal contexts use ‘votre’.

Cultural Tip
In France, ‘pièce d'identité’ most often refers to a passport (passeport) or the national ID card (carte d'identité). For proof of income, common documents are the latest payslips (bulletins de salaire), tax notice (avis d'imposition) or a bank statement. When speaking to strangers or in official settings, prefer the formal ‘votre’ instead of ‘ta’.
