debit card is similar to credit card except it is prepaid value. I dont think we can use a normal debit card for registration with paypal since they require you to have the access to your bank statement for the unique generated confirmation code display on the statement for final confirmation.

So you can either use the old way to fax the details back or consume a debit card online with the platform for you to login to check balance. I got one of the virtual debit card from a company called PaymentAsia

It is quite no choice if you need to use payapl for purchasing but if you are looking for a way to collect payments maybe you can simply try to apply for a payment gateway/ merchant account.
