ç) that the data read from the identification documents are not registered in a chronological order during the voting day;
d) that it registers the data of an identification document only once, regardless of the number of times the machine reads the document.

5. The final technical characteristics and the specifications regarding the devices, and the method of operation and control are determined in the normative act of the CEC.
