PayPal does offer a debit like card that is associated with your PayPal balance. We use it to make purchases (credit card style) for we need for the store (i.e. yarn, material, labels, etc). As long as you use like a credit card and do not enter a pin there are no fees assoicated with the use.
I did register to use the PayPal card reader, however, it will not work with my android style phone. We went to Sqaure.com and orderd this card reader and so far so good.
