Good Friday, Bad OS: Store Closed, But Computer Opened Doors For Shoppers Anyway

April 27th, 2011

The Pak ‘n Save’s owner, Glenn Miller, was reportedly furious about the incident at first, but calmed down after he saw the security footage, including images of the first customer, who arrived with a young child, spent 20 minutes shopping, paid for her purchases and left. “I still think she probably doesn’t know we weren’t there. It is the funniest thing. You just have to laugh your head off when you watch,” Miller said.

“They weren’t in for a free-for-all. They were doing their normal shopping and then got to the checkout. Half of them paid and the other half thought ‘This is a good deal’ and walked out. I can certainly see the funny side of it, but I’d rather not have the publicity, to be honest. It makes me look a bit of a dickhead.” (That’s apparently a much less impolite term in New Zealand.)

Still open is the question of why the system that automatically opens the store—doors, lights and everything else that signaled to customers that the Pak ‘n Save was open for business—was able to operate without human intervention.

Mis-programming a holiday isn’t that surprising. It’s easy to assume that someone else has already programmed “don’t open this Friday” into the system, and the user interfaces for physical-plant automation are often cryptic at best. (And at a time when iPhones can’t even figure out how to manage the shift to Daylight time properly, the bar for automatic scheduling of a movable religious holiday is pretty low.)

But who came up with the brilliant idea of automatically opening a store completely without human intervention? You’ll always want the ability for a human manager to override the automation. But it’s even more critical to be sure that the automation doesn’t do its thing when there are no store personnel around. You’ll never want to unlock the doors without someone on site.

There should have been a button, a switch, something that, unless it was pushed, would prevent the store-opening process from proceeding. That’s the time when you want human intervention in the process.

It’s nice that half the customers paid for their groceries without prompting. It’s also nice that checkout automation made that possible, once they were in the door.

But it is possible for automation to be too reliable. And it’s always going to be more reliable than the honesty of customers.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
