Is it possible to transfer money from my shopfiy account into my debit or credit card without using a bank account?
Hello,
A card is just a tool to initiate a transfer between two money holding accounts - you can’t store money on it. Your credit card has an account - it just doesn’t feel like it.
The money always needs to be in some kind of account - bank, e-wallet etc
If you are in the US you could use Shopify Balance Managing your Shopify Balance account · Shopify Help Center
So what does that mean exactly?
It means no.
