World View | The Frying Dutchman

Wherein our intrepid CISO columnist wonders about the security mechanisms for self-service checkout at a Dutch grocery store. Warning: not for the faint of heart.

February 27, 2008 — CSO — As European stereotypes go, it is supposed to be the Hungarians who are mad. But I actually came across a mad Dutchman last weekend at the supermarket. Well, he wasn’t just any Dutchman--he was my next-door neighbour. He wasn’t exactly mad, either, but rather in a state of delirious exaltation. OK, enough of the disclaimers. We met in the local Albert Heijn, which is a national grocery chain in the Netherlands.

With the scanner in hand, you are now free to roam the store happily placing groceries in your trolley and scanning them as you go. When you get to the self-service check out, the scanner gives you the bad news of your total. You pay with your bank debit card, and voila, you’re out the store and headed home on your bicycle.

It was then that it hit me. What was to prevent you from filching the groceries and making off with your own little Dutch treat? I thought about it for a moment. Unlike American self-service checkouts, there was no weighing of articles to ensure that the packages
