The MUX unified registration service is a service that AOC makes available to Catalan public administrations that allows the integration of AOC services with the general entry and exit register of each body.
With this integration, entries of entry or exit entries generated by the services of the AOC are made directly in the general register of the organization instead of being made in the auxiliary electronic register of the EACAT. Rules can be defined that allow different registrations to be settled depending on the request parameters that are established.
