German bank cards usually cannot accept US dollars directly, because the standard currency in Germany is Euro. German bank cards generally only support euros or other currencies, but a few banks allow customers to receive dollars in their bank cards. If you need to receive US dollars, you can consider opening a US dollar account or using foreign exchange transfer service. You can contact Deutsche Bank for advice on how to open these services.

If you want to receive dollars from the United States or other places, you can send them to your German bank account by transfer or remittance. In this case, banks usually use exchange rate conversion to convert dollars into euros or other currencies, and then deposit these currencies into your account. In this case, you need to consult the bank about the cost of exchange rate conversion and transfer and the details related to the process.
