Please help me. Maybe this is the right place to ask regarding this: How can I send money to a debit or credit card?

Yes. I do not want to charge the card, not reimburse a charge, no, I want to send money to a credit card or debit card. I need this as a solution for a business.

It can't be so hard. If you ever got your VAT/Sales tax reimbursed in Europe (e.g. via this service provider: https://www.globalblue.com/ ) you know what I mean. It does not require you to have bought the goods with a credit card. They just send you the credit to your card that your provide.

How can I do this?
