Method for managing an opening state of a value container by means of a suitable system, which comprises the value container and a computing unit spatially separated from the value container and having a first detection unit, wherein the value container comprises a lockable and unlockable security device and a second detection unit, comprising the following steps: Capturing a biometric data set of a user by means of the first capture unit, wherein the biometric data set is not stored in the system, Converting the biometric data set by means of a second generating process and storing it in a first numerical data set by the computing unit, Executing a first generating process which generates a first opening code on the basis of at least the first numerical data set and at least one further data set (D3, D4) by means of the first computing unit, wherein the at least one further data set (D3, D4) is selected from a serial number of the value container and information relating to a location of the value container, wherein the first numerical data set is only used to generate the opening code and is subsequently cancelled, Outputting the first opening code by transmission to a mobile terminal of a user, Transmitting the first opening code to the value container via an operating unit (4a, 4b) by the user and followed by Capturing the biometric data set of the user by means of the second capture unit, Converting the biometric data record into a second numerical data record by means of the second generating process, Re-executing the first generating process by the arithmetic unit associated with the value container, which generates a second opening code on the basis of at least the second numerical data set and the at least one further data set (D3, D4), Comparing the first and the second opening code by the computing unit assigned to the secure storage unit, Unlocking the security device if the first and the second opening code match according to the comparison step, wherein the system is free of a data connection between the value container and the computing unit, wherein the first and second generating processes are deterministic and/or the first and the second opening code are one-time codes.
