Method for inspecting an individual possessing an identity document comprising an automatic reading zone in which a number of the document is present and an electronic chip in which an item of biometric data for authenticating the individual is stored, the method comprising: - during a first step carried out by a first inspection device, -- acquisition of a first item of biometric data on a biometric trait of the individual, -- acquisition of the number of the identity document of the individual by reading the automatic reading zone of the identity document, and -- recording, in a remote memory, of the number related to the item of biometric data of the individual, and - during a second step carried out by a second inspection device, -- acquisition of a second item of biometric data on the same biometric trait of the individual as that on which the first item of data was acquired, -- on the basis of the second item of biometric data, recovery, in the memory, of the identity document number corresponding to the biometric trait of the individual, -- on the basis of the number of the identity document of the individual, access to the contents of the electronic chip of the identity document and recovery of the item of authentication biometric data, and -- implementation of biometric authentication of the individual by comparing the item of authentication biometric data stored in the chip and an item of biometric data acquired by the second inspection device. - during a first step carried out by a first inspection device, -- acquisition of a first item of biometric data on a biometric trait of the individual, -- acquisition of the number of the identity document of the individual by reading the automatic reading zone of the identity document, and -- recording, in a remote memory, of the number related to the item of biometric data of the individual, and -- acquisition of a first item of biometric data on a biometric trait of the individual, -- acquisition of the number of the identity document of the individual by reading the automatic reading zone of the identity document, and -- recording, in a remote memory, of the number related to the item of biometric data of the individual, and - during a second step carried out by a second inspection device, -- acquisition of a second item of biometric data on the same biometric trait of the individual as that on which the first item of data was acquired, -- on the basis of the second item of biometric data, recovery, in the memory, of the identity document number corresponding to the biometric trait of the individual, -- on the basis of the number of the identity document of the individual, access to the contents of the electronic chip of the identity document and recovery of the item of authentication biometric data, and -- implementation of biometric authentication of the individual by comparing the item of authentication biometric data stored in the chip and an item of biometric data acquired by the second inspection device. -- acquisition of a second item of biometric data on the same biometric trait of the individual as that on which the first item of data was acquired, -- on the basis of the second item of biometric data, recovery, in the memory, of the identity document number corresponding to the biometric trait of the individual, -- on the basis of the number of the identity document of the individual, access to the contents of the electronic chip of the identity document and recovery of the item of authentication biometric data, and -- implementation of biometric authentication of the individual by comparing the item of authentication biometric data stored in the chip and an item of biometric data acquired by the second inspection device.
