Identification, authentication and authorization method in a laboratory system comprising at least one laboratory device, the method comprising: - receiving identification data from an identification tag by an identification and authentication unit, the identification data identifying a user; - receiving identity confirmation data by the identification and authentication unit to authenticate the user; - generating authentication data corresponding to the identification data upon successful authentication of the user, the authentication data comprising a validity time period, wherein the authentication data is configured to enable authentication of the user based on the identification data during the validity time period without repeated receipt of the identity confirmation data; - receiving the identification data by an identification unit from the identification tag; - validating the authentication data corresponding to the identification data comprising the step of verifying non-expiry of the validity time period; - granting authorization to the user for the laboratory device upon successful validation of the authentication data; - the identification and authentication unit encrypting and/or digitally signing the authentication data; - the identification unit decrypting and/or verifying a digital signature of the authentication data; - the identification and authentication unit causing the authentication data to be stored on the identification tag - for example by means of an identification tag writer - wherein the identification tag is a writable identification tag; and - after identification of the user and before validation of the authentication data, the identification unit retrieving the authentication data from the identification tag. - receiving identification data from an identification tag by an identification and authentication unit, the identification data identifying a user; - receiving identity confirmation data by the identification and authentication unit to authenticate the user; - generating authentication data corresponding to the identification data upon successful authentication of the user, the authentication data comprising a validity time period, wherein the authentication data is configured to enable authentication of the user based on the identification data during the validity time period without repeated receipt of the identity confirmation data; - receiving the identification data by an identification unit from the identification tag; - validating the authentication data corresponding to the identification data comprising the step of verifying non-expiry of the validity time period; - granting authorization to the user for the laboratory device upon successful validation of the authentication data; - the identification and authentication unit encrypting and/or digitally signing the authentication data; - the identification unit decrypting and/or verifying a digital signature of the authentication data; - the identification and authentication unit causing the authentication data to be stored on the identification tag - for example by means of an identification tag writer - wherein the identification tag is a writable identification tag; and - after identification of the user and before validation of the authentication data, the identification unit retrieving the authentication data from the identification tag.
