With the free OFK app, registered customers of OFK GmbH Kampe can register their carcass collections online. To use the app, prior telephone activation is required for each customer number. In the app you can activate and enter multiple customer numbers and also store one or more favorite animal species for each customer number. When registering large animals that require ear tags, it is necessary to correctly enter the ear tag and date of birth of each animal. To make this easier, you can use the barcode scanner in the app to enter this data directly from the animal passport.
