the first offer I found for the first offer i found for german CC terminals (sumup.de): - 2.75% on credit card tx - .95% on EC tc (popular form of debit cards) - no base fee

I only found secondary sources for the direct way, but they state (zahlungsverkehrsfrafen.de) - .3%, at least .08€ for EC tx - 2-4% for CC tx, depending on provider
