iDeal is the most popular online payment method in the Netherlands, and from today on you can also use apps to count in the Play Store.
Some Android users could already a few months pay with iDeal, but the support is there now for everyone. Previously you could only pay with a credit card or PayPal, for many Dutch is somewhat more time-consuming. A gift card with the Play Store credit was (and is) also already an option.
Checkout with paypal works in the Play Store just like you used to do online banking with an online store. How that looks, you can see in the below video. In this way you can not only new apps you buy, you can iDeal also to use in-app purchases for the apps that you have already installed.
