Yordex offers prepaid MasterCards. This means every individual card has to be topped up. This is different from debit and credit cards that don’t have a balance per card.
The benefit of this is that you have more control over spend. Subscriptions cannot continue running and employees cannot spend if it was not approved.
In most cases we will automatically top up the card, but you can also manually top up cards. See this article with more details about topping up cards.
