Who can use PayPal?

Anyone can use PayPal.

If you have a PayPal account you can donate using your bank account or credit card.

If you do not have a PayPal account, you can donate using a credit card (though unfortunately not a Laser card as yet)

PayPal is the worlds leading payment processor, and allows you to make a donation safely while keeping all your address and bank/credit card details unseen from the receiver.
