It doesn't matter to PayPal how people pay them. You still get the money to your account.
People can opt to use a credit card, or have it deducted from their checking account. That doesn't matter for your receipt of the money.
Same the other way. As long as you've got a mechanism to put money in your PayPal account (which you have to have to set one up), then there's no problem.
PayPal is just the go-between.
I think paypal charges a fee to take credit cards for you. Not sure on that though. It does cost THEM to be able to take them so it makes sense they would add a small fee to accounts that use them on the incoming side.
Ok...now it seems like I recall when I was doing troop support that I could not accept credit card donations because I didn't have a Paypal premiere account...I just had a free personal account.
That's why I'm worried, because if they try to pay me with a credit card, I was under the impression my account won't allow it.
It's been a long time,however, and I may be remembering wrong...
