CELI, or Certificato Elettronico di Identità, is an electronic identity certificate used in Italy. It serves as a digital identity for individuals, allowing them to access online services securely. CELI is designed to enhance online transactions and interactions with public and private entities. The certificate is issued by authorized providers and includes personal information, ensuring that users can authenticate their identity. By using CELI, individuals can sign documents electronically and access various online platforms, streamlining processes that traditionally required physical presence or paperwork.
