A bunch of Belgian banks have decided to get out of the ATM-operating business. A new company (perhaps set up by a consortium of banks) is establishing cash points. Bank ATMs are disappearing. The two cash points I saw today in Antwerp were in nice-looking storefronts labeled "Bancontact". The one I used had three ATMs.
I don't know how new this is, but I suspect there's a software issue that could affect some US visitors. Two different ATMs (at the same location) ate my debit cards today. The first message said my card had expired--which I didn't know was a thing with debit cards--and that I should contact my bank. I've had neither an email nor a text from Capital One about receiving a replacement card, so I am very doubtful there is a problem with the card that would justify its retention by the ATM.
Someone with a Wells Fargo card used one of the other ATMs successfully, so I decided to try my second ATM card in that machine. (My trip ends in five days; otherwise, I wouldn't have made the second attempt.) That second card was from my credit union. I think the ATM message was the same as before. In any case, the result was the same: My card was retaimed by the ATM. (Although the machines looked new and had tap points, I had to insert both cards.) It seems extraordinarily unlikely there is a problem with both my debit cards, which are used only in ATMs and only by me.
There was a large sign on the wall of the storefront, only in Dutch, which said (I think--I do not know Dutch) that one should call 0800 713 02 Mon-Sat 0800-1800 if there were issues. So I did that, three times over the course of the day. I got only a recording (repeated in English) that said Proximus (sp?) couldn't answer the phone then and I should call later. There was no way to leave a message.
I'll try to call again on Monday, but I have no reason to think the company will be answering its phones then, either. I'll also try to notify the Antwerp tourist office, because there may be serious issues with this rollout. If they're retaining people's ATM cards without reason, that is not good. It could be a real problem if it happened to someone at the beginning of a trip.
