Giuliano If you make such a claim that your card didn’t work at least five times - and you can clearly remember that - than you should be able to give more information on that matter. It shouldn’t be too hard to name that specific hotel you stayed in Las Vegas unless you switched your hotel every day and stayed at ten different hotels. So if you want to help bunq to figure out what went wrong you should give more informations about each case.
I travel a lot to Russia and the US too and I haven’t had a single transaction being denied with my bunq card because it was a debit card. I even book my flights, hotels and rental cars with either my bunq or N26 Mastercard and I cannot remember a single time that my card wasn’t accepted. IF my card was denied it was allows because I messed things up like setting the limit too low or connecting my card to the wrong account where the balance wasn’t high enough or using the dual pin feature which doesn’t work at offline terminals.
The point I’m trying to make is in 99 % the card works like any other credit card does too. And if it doesn’t there usually was a user error that resolved in a payment being denied. I don’t see any additional value in a credit card. I have been traveling for years with a credit card as backup just because it was free from my old bank and the last time I used it was back in 2013 then I canceled it. Ever since I only use debit mastercards.
