“Currently we use CarontePass to access Kreitek, our Hackerspace from Tenerife (Spain) This carontepass is an improvement of the previous project (v1) It is difficult to create a makerspace (or other collaborative space) but once you have the tools you want them to be used as much as possible. They also have users who want to use them. We only need one thing, that can be used on a schedule. But here we have a big problem, if we have 30 users for example… Do we have to make 30 copies of door keys? What happens if one gets those keys lost? Did we change them all? It would be a serious security breach.”
