Credit Card Chips Have Failed to Halt Fraud (So Far) (fortune.com)
An anonymous reader quotes Fortune:
New chip-enabled credit cards, which were rolled out to U.S. consumers starting in 2015, were supposed to put an end to rampant credit card fraud. So much for that. A new report from the research firm Gemini Advisory has found that, of more than 60 million cases of credit card theft in the last 12 months, a whopping 93% of the stolen cards had the new chip technology...
In theory, EMV should reduce fraud because every card transaction requires an encrypted connection between the chip card and the merchant's point-of-sale terminal... But while the EMV standard is supposed to ensure the card data cannot be captured, many merchants are failing to properly configure their systems, according to a Gemini Advisory executive who spoke with Fortune... The upshot is that criminals have been able to insert themselves into the transaction data steam, either by hacking into merchant networks or installing skimmer devices in order to capture card information... The report concludes by noting that big merchants have begun to tighten up their implementation of the EMV system, which will make them less of a target. Instead, criminals are likely to begin focusing on smaller businesses.
The report estimates that in just the last twelve months, 41.6 million records have been stolen from chip-enabled cards.

The US opted for chip+signature, rather than chip+PIN like the rest of the world. Since no one ever checks signatures properly, stolen cards can easily be used for fraud in the US, without needing to shoulder surf for a PIN first.
I got this same explanation from a waitress, that they didn't use pin because of tipping... But that's utterly ridiculous, in the rest of the world they bring a wireless payment device to your table and it asks if you'd like to leave a tip, you enter the amount to tip and it calculates the total and then authorises the total using your pin. The payment device then prints out a receipt which shows how much you paid in total.

While we're talking about obsolete practices, could we please abolish tipping, too?
And for those of us in the rest of the world, the US is also the cause of fraud on our credit cards. For backward compatibility, our cards still have a magstripe, but the bank's won't authorise payment in local country. So we get our cards cloned, and then used in the US!
Here in Norway they've fixed this quite easily because around 2010 most the banks introduced regional blocks, the defaults vary a little but my bank's card by default only works in Norway. To expand the coverage you must log in to the online bank and enable it. You can permanently enable it for our neighboring countries in Scandinavia, but for the other regions (rest of Europe, North America, South America, Africa, Asia) you can only enable it for three months at a time. That has pretty much stopped international scams dead in their tracks, even if it is enabled the crooks don't know until they try and while the occasional tourist will forget and enabled it after being declined it will stand out as a sore thumb.
Combined with 2FA using the cell phone/one time codes for online purchases fraud here is extremely low. I found a page that said total credit/debit card fraud in Norway is around 150 MNOK/year, that's $17 million. Divided by 2.4 million households that's about $7, the average household income is about $51k so 0.013% is lost to fraud. Basically that's noise level, people lose more money on grocery prices due to shoplifting than that. I don't think these numbers include robbery where you're forced to enter/hand over the PIN though, just shoulder surfing and such.

There's a lot of misinformation here.
Chip cards aren't meant to prevent card breaches. For card-present transactions (in person at the store), the exact same encryption and cardholder data protection requirements are in place from the reader to the bank whether its EMV or old mag-stripe. For card-not-present transactions (online and e-commerce) EMV makes no difference at all.
Chip cards do one thing. They make it harder to make a fraudulent physical card. With mag-stripe it is trivial to take another credit card or even a subway gift card and recode its mag-stripe to use a stolen card number, so I can walk into a merchant and use that card.
The author appears to be confusing EMV standards with the PCI P2PE (point to point encryption) standard, which is meant to prevent breaches by doing many of the things the author describes.
