As provided for by the Code of criminal procedure, an EIO may be issued in order to determine whether a physical or moral person holds or controls one or more accounts in a banking or financial establishment or to obtain information about a specified bank account or a banking transaction during a specific period of time (art. 694-27).
The issuing magistrate shall provide the reasons for which he considers that the information requested helps to establish the truth and the reasons for which he or she assumes that the banks located in the executing State hold an account and, where necessary, the banks that might be concerned.
At section H4 of Annex A, the issuing authority may request the following information: the bank accounts held by a person, the account number, the name of the banking or financial establishment, the body address, a copy of the bank holder signature, the identity of the persons having the power of attorney and the copy of their signature, the copies of bank statements for a specified period, the copies of cheques with numbers, etc.
The Code of criminal procedure allows the magistrate to ask any person, private or public institution, or public administration likely to have information relevant to the investigation to hand over this information, without being subject to the obligation of professional secrecy except with legitimate reasons.
Furthermore, Article 694-49 of the Code of criminal procedure specifies that when the issuing State requests, under an EIO, the execution of an investigative measure that requires evidence to be obtained in real time, on a continuous basis and over a specific period of time, the practical details of the measure shall be determined by mutual agreement between the magistrate to whom the request is addressed and the competent authority of the issuing State. These provisions shall apply in particular to the monitoring of banking or other financial transactions carried out on one or more specific accounts.
