Can I pay with a google present card

Hi Folks,

I guess this one is easy, but since I am new to this app as well as smartphone paying in general, I am not sure.

I dont want to enter my credit card and like to pay via some pre-pay modell. Is it possible to pay with something like [1]. If not, what is meant by “enter code” as payment method and where can I get those.

Thank you and bye,

Sven
