Sorry for the Dunglish :) Exactly that, we usually use my pass when going out, I couple it to the "beer" account and send everyone a payment request, or just my bunq.me page (like https://bunq.me/freekvh (try adding an amount to the url and then a word and see the page change dynamically, i.e. https://bunq.me/freekvh/10.15/beer_money) and they can fill the beer account (iDeal is the instant payment method in the Netherlands). I set another pin code on the fly for the pass or even choose 2 pin codes to access different accounts with each. But usually one pays "contactless" in the Netherlands.

For work I do the same, create a dedicated account and after a trip I can easily export an overview to get the money back from the company.

In the Netherlands one pays with Maestro cards but for international travel I can couple a (debit) MasterCard, or the new TravelCard which is a real credit MasterCard but backed by your own money. bunq does not do debt.
