This is exactly the same version of MIFARE Classic Tool (MCT) as the free one!
(Except it will not show the donate notice at startup/updates.)
If you like MCT and want to support the developer, please consider to buy this app. You will get the exact same version of MCT but in addition, a good feeling for supporting free and open source software ;)
