Automatic code for Visitors of a Museum

we are an association in a village in brandenburg and have a small museum. We are looking for a solution, where visitors give us some data and then get a code to open the door. The code should only work once and should be valid for only one day. Is this possible with nuki solutions? Which ones do we need? Do you know a distributor, who could install this for us?
Thanks a lot! Kind regards, Ulrich Dahl
