It’s a scenario most people have encountered: you try to make a big or unexpected purchase on your credit card, and, at the moment you need it the most, the card gets declined.
Sometimes, it’s as simple as confirming the purchase via text message, and you can quickly complete the transaction. Other times, it’s a days-long process that involves confirmation codes, mailed letters and waiting on hold with the card company to validate that it was indeed you who wanted to buy the product.
The rate of fraud alerts is “absolutely” going up, according to Deloitte U.S. risk & financial advisory principal Satish Lalchand.
It can’t be ignored, because many of the alerts are not false alarms.
About 60% of credit card holders in 2023 experienced some sort of attempted fraud, according to Experian.
“Fraud in general across all channels, whether it’s check fraud, credit card fraud payments, the peer-to-peer payments, everything, is significantly increasing at a very rapid pace,” Lalchand said.
Global card losses attributed to fraud reached $33 billion in 2022, according to payments industry research company Nilson Report, with the U.S. market representing roughly 40% of losses. It has forecast a persistent threat that could reach nearly $400 billion in card fraud in the decade to 2032.
“What’s driving a lot of this type of fraud, is the fraudsters themselves are using AI in general,” Lalchand said. “So, they are able to now move much faster.”
In the past, cybercriminals could open five to ten accounts a day. Now, it’s hundreds, if not thousands of accounts, thanks to advancements in artificial intelligence.
But at the same time AI is helping to detect potentially problematic transactions, with the downside of many cases turning out to be false alarms.
“When we come down to credit cards, financial institutions are investing more in the concept of fraud and fraud modernization, replacing older technology and having better fraud detection capabilities, and retuning their alerts,” Lalchand said. “That’s also causing a lot more on the detection side to go up.”
More personal data is being stolen
Michael Bruemmer, Experian vice president and head of its global data breach resolution and consumer protection division, says a lot more fraud is being done in other ways than stealing your credit card number, using other portions of your financial background, identity background, social security number.
Just in the past five months, there have been four major data breaches including Ticketmaster, Change Healthcare, AT&T and National Public Data. More data breaches can lead to more scrutiny and more preemptive alert protocols, although they are often not the main reason for alerts, according to Experian.
There is some good news. Overall, the rate of false purchases on credit cards is actually decreasing, according to Experian. There have been 416,582 cases of credit card fraud that have been perpetrated in 2024. It’s down 5.4% versus 2023.
AI’s ability to detect patterns based on previous behavior has helped. While you may still get credit card blocks on purchases that seem out of the ordinary, technology has improved fraud alerts in other ways. MasterCard said it’s observed on average a 20% increase in its ability to detect fraud thanks to AI, and up to 300% increase in its ability to detect fraud without more false alerts. Mastercard declined to provide statistics on the absolute level of fraud and overall accuracy of fraud detection.
“We’ve come such a long way to actually reduce the friction out there,” said Johan Gerber, Mastercard executive vice president and head of security solutions.
Take for example, travel plans and making purchases in a foreign country. Before, people would have to call the credit card company. Now, card companies automatically note vacations and travel patterns based on past purchase behavior. Technology has also made it faster to identify and clear flagged fraud alerts if it is indeed a false alarm. Instead of having to call and wait on hold, in many cases verification can be done in a matter of minutes through authorized related accounts or through information only the individual cardholder would know.
Tips to cut down on unnecessary alerts
Today, some scenarios will raise concerns within current security parameters. Experian notes that while data breaches may turn up the dial on fraud alerts, it’s actually changes in shopping patterns that are guaranteed to set off red flags. If you’re buying something at a new store or purchasing a big ticket item that you don’t usually buy, that’s typically something that will be noted. MasterCard also said trying multiple transactions quickly in a row will always alert their systems. So, you can expect these will usually garner some sort of temporary block.
“It’s a balance,” Gerber said. “Do I want to be inconvenienced? Do you potentially want a transaction that [MasterCard] may get wrong because [we] declined you? Or do I want to sit on the other side of the loss of trust in that [we] actually did let a transaction through and you should have known it’s not me.”
Other things you can do to ensure that you get mostly accurate fraud alerts is to sign up for monitoring services and personally set limit alerts on your accounts. Most institutions will let you place monetary limits on when you can get notified about big transactions. Freezing your credit file, using a password manager and using two-factor authentication for your financial accounts with a biometric passcode can also be beneficial.
“Try to shop on regular, reputable shopping sites, and if you’re going to use a credit card, have a low-level limit credit card that’s only used for those shopping sites,” Bruemmer said. “I would also recommend using a tap-to-pay or a mobile app and then make sure you’re not shopping on a public Wi-Fi network.”
And, even if the alerts may be annoying, never ignore them. Even though it may seem like you get notice of a data breach every day, it doesn’t mean you won’t eventually be affected.
“Consumers should pay attention to all of this, because it’s just a matter of time … they will be impacted,” Lachland said.

Artificial intelligence is shaking up the advertising business and “unnerving” investors, one industry leader told CNBC.
“I think this AI disruption … unnerving investors in every industry, and it’s totally disrupting our business,” Mark Read, the outgoing CEO of British advertising group WPP, told CNBC’s Karen Tso on Tuesday.
The advertising market is under threat from emerging generative AI tools that can be used to materialize pieces of content at rapid pace. The past couple of years has seen the rise of a number of AI image generators, including OpenAI’s DALL-E, Google’s Veo and Midjourney.
In his first interview since announcing he would step down as WPP boss, Read said that AI is “going to totally revolutionize our business.”
“AI is going to make all the world’s expertise available to everybody at extremely low cost,” he said at London Tech Week. “The best lawyer, the best psychologist, the best radiologist, the best accountant, and indeed, the best advertising creatives and marketing people often will be an AI, you know, will be driven by AI.”
Read said that 50,000 WPP employees now use WPP Open, the company’s own AI-powered marketing platform.
“That, I think, is my legacy in many ways,” he added.
Structural pressure on creative parts of the ad business are driving industry consolidation, Read also noted, adding that companies would need to “embrace” the way in which AI would impact everything from creating briefs and media plans to optimizing campaigns.
A report from Forrester released in June last year showed that more than 60% of U.S. ad agencies are already making use of generative AI, with a further 31% saying they’re exploring use cases for the technology.
‘Huge transformation’
Read is not alone in this view. Advertising is undergoing a “huge transformation” due to the disruptive effects of AI, French advertising giant Publicis Groupe’s CEO Maurice Levy told CNBC at the Viva Tech conference in Paris.
He noted that AI image and video generation tools are speeding up content production drastically, while automated messaging systems can now achieve “personalization at scale like never before.”

However, the Publicis chief stressed that AI should only be considered a tool that people can use to augment their lives.
“We should not believe that AI is more than a tool,” he added.
And while AI is likely to impact some jobs, Levy ultimately thinks it will create more roles than it destroys.
“Will AI replace me, and will AI kill some jobs? I think that AI, yes, will destroy some jobs,” Levy conceded. However, he added that, “more importantly, AI will transform jobs and will create more jobs. So the net balance will be probably positive.”
This, he says, would be in keeping with the labor impacts of previous technological inventions like the internet and smartphones.
“There will be more autonomous work,” Levy added.
Still, Nicole Denman Greene, analyst at Gartner, warns brands should be wary of causing a negative reaction from consumers who are skeptical of AI’s impact on human creativity.
According to a Gartner survey from September, 82% of consumers said firms using generative AI should prioritize preserving human jobs, even if it means lower profits.
“Pivot from what AI can do to what it should do in advertising,” Greene told CNBC.
“What it should do is help create groundbreaking insights, unique execution to reach diverse and niche audiences, push boundaries on what ‘marketing’ is and deliver more brand differentiated, helpful and relevant personalized experiences, including deliver on the promise of hyper-personalization.”

Nvidia boss Jensen Huang has been on a tour of Europe this week, bringing excitement and intrigue to everywhere he visited.
His message was clear — Nvidia is the company that can help Europe build its artificial intelligence infrastructure so the region can take control of its own destiny with the transformative technology.
I’ve been in London and Paris this week following Huang around as he met with U.K. Prime Minister Keir Starmer, French President Emmanuel Macron, journalists, fans, analysts and gave a keynote at Nvidia’s GTC event in the capital of France.
Here’s the what I saw and the key things I learned.
At London Tech Week, the lines were long and the auditorium packed to hear him speak.
The GTC event in Paris was full too. It was like going to a music concert or sporting event. There were GTC Paris T-shirts on the back of every chair and even a merchandise store.

The aura of Huang really struck me when, after a question-and-answer session with him and a room full of attendees, most people lined up to take pictures or selfies with him.
Macron and Starmer both wanted to be seen on stage with him.
Nvidia positions itself as Europe’s AI hope
Nvidia’s key product is its graphics processing units (GPU) that are used to train and execute AI applications.
But Huang has positioned Nvidia as more than a chip company. During the week, he described Nvidia as an infrastructure firm. He also said AI should be seen as infrastructure like electricity.
His pitch to all countries was that Nvidia could be the company that will help countries build out that infrastructure.
“We believe that in order to compete, in order to build a meaningful ecosystem, Europe needs to come together and build capacity that is joint,” Huang said during a speech at the Viva Tech conference in Paris on Wednesday.

One of the most significant partnerships announced this week is between French startup Mistral and Nvidia to build a so-called AI cloud using the latter’s GPUs.
Huang spoke a lot during the week about “sovereign AI” — the concept of building data centers within a country’s borders that services its population rather than relying on servers located overseas. Among European policymakers and companies, this has been an important topic.
Huang also heaped praise on the U.K., France and Europe more broadly when it came to their potential in the AI industry.
China still behind but catching up
On Thursday, Huang decided to do a tour of Nvidia’s booth and I managed to catch him to get a few words on CNBC’s “Squawk Box Europe.”
A key topic of that discussion was China. Nvidia has not been able to sell its most advanced chips to China because of U.S. export controls and even less sophisticated semiconductors are being blocked. In its last quarterly results, Nvidia took a $4.5 billion hit on unsold inventory.
I asked Huang about how China was progressing with AI chips, in particular referencing Huawei, the Chinese tech giant that is trying to make semiconductor products to rival Nvidia.
Huang said Huawei is a generation behind Nvidia. But because there is lots of energy in China, Huawei can just use more chips to get results.
“If the United States doesn’t want to partake, participate in China, Huawei has got China covered, and Huawei has got everybody else covered,” Huang said.
In addition, Huang is concerned about the strategic importance of U.S. companies not having access to China.
“It’s even more important that the American technology stack is what AI developers around the world build on,” Huang said.
Just reading between the lines somewhat — Huang sees a world where Chinese AI tech advances. Some countries may decide to build their AI infrastructure with Chinese companies rather than American. That in turn could give Chinese companies a chance to be in the AI race.
Quantum, robotics and driverless is the future
Huang often uses public appearances to talk about the future.
I asked him about some of those areas he’s bullish on like robotics and driverless cars, technology that Nvidia’s products can power.
Huang told me this will be the “decade of” autonomous vehicles and robotics.

During his keynote at GTC Paris on Wednesday, he also address quantum computing, saying the technology is reaching “an inflection point.”
Quantum computers are widely believed to be able to solve complex problems that classic computers can’t. This could include things like discovering new drugs or materials.

With Elon Musk looking to June 22 as his tentative start date for Tesla’s pilot robotaxi service in Austin, Texas, protesters are voicing their opposition.
Public safety advocates and political protesters, upset with Musk’s work with the Trump administration, joined together in downtown Austin on Thursday to express their concerns about the robotaxi launch. Members of the Dawn Project, Tesla Takedown and Resist Austin say that Tesla’s partially automated driving systems have safety problems.
Tesla sells its cars with a standard Autopilot package, or a premium Full Self-Driving option (also known as FSD or FSD supervised), in the U.S. Automobiles with these systems, which include features like automatic lane keeping, steering and parking, have been involved in dozens of collisions, some fatal, according to data tracked by the National Highway Traffic Safety Administration.
Tesla’s robotaxis, which Musk showed off in a video clip on X earlier this week, are new versions of the company’s popular Model Y vehicles, equipped with a future release of Tesla’s FSD software. That “unsupervised” FSD, or robotaxi technology, is not yet available to the public.
Tesla critics with The Dawn Project, which calls itself a tech-safety and security education business, brought a version of Model Y with relatively recent FSD software (version 2025.14.9) to show residents of Austin how it works.
In their demonstration on Thursday, they showed how a Tesla with FSD engaged zoomed past a school bus with a stop sign held out and ran over a child-sized mannequin that they put in front of the vehicle.
Dawn Project CEO Dan O’Dowd also runs Green Hills Software, which sells technology to Tesla competitors, including Ford and Toyota.
Stephanie Gomez, who attended the demonstration, told CNBC that she didn’t like the role Musk had been playing in the government. Additionally, she said she has no confidence in Tesla’s safety standards and said there’s been a lack of transparency from Tesla regarding how its robotaxis will work.
Another protester, Silvia Revelis, said she also opposed Musk’s political activity, but that safety is the biggest concern.
“Citizens have not been able to get safety testing results,” she said. “Musk believes he’s above the law.”
Tesla didn’t immediately respond to a request for comment.
