assigning an individual code to each of the multitude of coordinate measuring devices;
providing the individual code of a first coordinate measuring device on the first coordinate measuring device; and
pairing the first coordinate measuring device with a mobile device of the owner or user of the first coordinate measuring device, particularly wherein the mobile device is a smartphone or a tablet computer,

wherein the pairing comprises:
capturing, by the mobile device, the individual code of the first coordinate measuring device;
establishing a remote data connection between the mobile device and the computational environment;
sending the captured individual code together with an identifier of the mobile device or of a user of the mobile device from the mobile device to the computational environment via the established data connection; and
verifying, at the computational environment, the sent individual code and, in case of a positive result of the verification, storing the identifier of the mobile device assigned to the digital twin of the first coordinate measuring device,

wherein the method further comprises:
sending a request from the mobile device to the computational environment for information about the first coordinate measuring device together with the identifier of the mobile device; and
determining a validity of the request based on the stored identifier and the sent identifier;

wherein, if the request is determined to be valid, the method further comprises:
retrieving the requested information from the individual digital twin of the first coordinate measuring device and sending the requested information to the mobile device; and
providing the information about the first coordinate measuring device on a display of the mobile device to the user of the mobile device.

2. The method according to claim 1 , wherein the computational environment comprises one or more server computers or a cloud-computing environment of a manufacturer of the first coordinate measuring device, wherein the pairing comprises:
sending owner or user information related to the owner or user of the first coordinate measuring device from the mobile device to the computational environment; and
storing the owner or user information in the digital-twin database, assigned to the individual digital twin of the first coordinate measuring device.

3. The method according to claim 1 , wherein
the information about the individual coordinate measuring devices in the digital-twin database comprises information about individual components of the respective individual coordinate measuring device; and
the provided information about the first coordinate measuring device comprises information about individual components of the first coordinate measuring device;

8. The method according to claim 1 , wherein sending the request comprises capturing, by the mobile device, the individual code of the first coordinate measuring device, and sending the captured individual code together with the request.

9. The method according to claim 1 , wherein the data connection between the first coordinate measuring device and the database is established using a cellular phone network and a subscriber identity module of the mobile device.

10. The method according to claim 9 , wherein the data connection is established via a SIM card or an embedded SIM of the mobile device.

11. The method according to claim 1 , wherein
information about the individual coordinate measuring device of each individual digital twin is continuously updated, and
retrieving the requested information from the individual digital twin of the first coordinate measuring device comprises retrieving the most recently updated information of the first coordinate measuring device.

12. The method according to claim 1 , wherein the first coordinate measuring device is a laser-based metrology device.

13. The method according to claim 12 , wherein the laser-based metrology device is a laser tracker, a laser scanner or a total station.

14. The method according to claim 1 , wherein the first coordinate measuring device is a coordinate measuring machine (CMM), particularly a portable articulated arm CMM or a stationary CMM.
