Sure it is possible.
Both the node-locked license and floating license are able to be purchased by credit card, if you don't have any PayPal account, email to mgtoolspro@gmail.com and we will send you a Paypal invoice to your email address so you can pay it using any credit card.
It is just for floating license it has to be a yearly payment instead of a monthly one, as after one year as the license gets expired we need to do it manually again.
This applies to both MGTools and MG-Picker Studio.
