Why that  charge on your statement could be fraud

NEWYou can now listen to Fox News articles!

A $4 charge is easy to ignore. It might appear as a parking fee, a small purchase or a vague merchant name that doesn’t raise any red flags. Consumer protection groups and law enforcement say scammers are counting on that.

Recent warnings describe a pattern sometimes called “ghost tapping,” where small, unfamiliar charges show up on contactless payment cards without a clear point of purchase. The amounts are easy to miss, but they can signal unauthorized access to your payment method rather than a simple billing error.

GHOST-TAPPING SCAM TARGETS TAP-TO-PAY USERS

How does ghost tapping work?

Better Business Bureau (BBB) warnings use the term “ghost tapping” to describe these incidents in consumer alerts. In simple terms, it means a payment can be triggered without you actively making a purchase.  

One reported method involves compromised payment terminals that quietly process low-value contactless charges. Another involves unauthorized NFC readers operating at close range, sometimes in crowded places. In these cases, a card or mobile wallet can be charged within inches.

Because these transactions run through standard contactless payment networks, they appear as normal card-present purchases. There is usually no clear sign on your statement that anything was wrong.

The small charges aren’t arbitrary

Low-dollar transactions are used to confirm that a card can be charged without being declined. When a small charge goes through, it signals that the payment details are active and usable. Once that charge goes through, it establishes a working payment path. Scammers can then run additional transactions using the same card details, sometimes across different merchants or terminals. Many people only notice these charges after they post to an account. At that point, the transaction appears as a completed purchase, not a pending authorization.

Why acting quickly matters

This means a charge that looks harmless could actually be the first step in a larger fraud attempt. Over time, these fraudulent charges may extend beyond a single card. If your payment details have been exposed or are stored in a compromised system, they can be reused until you cancel the card. That can result in multiple charges over several days or even billing cycles.

Delays in reporting also affect how quickly you can stop fraud. The Federal Trade Commission (FTC) advises you to report unauthorized charges as soon as they are identified. In practice, that means contacting your card issuer as soon as you see a charge you don’t recognize, either through the issuer’s app or customer service line.

Credit cards typically offer stronger fraud protections than debit cards, where money may be withdrawn directly from your bank account. Under federal law, liability for unauthorized credit card charges is limited, but those protections depend on when you report it.

Scammed? What federal agencies say to do next

If you spot a charge you don’t recognize, acting quickly can limit damage and protect your rights under federal law.

Review transactions as they post

The FTC recommends checking account activity regularly and flagging any unfamiliar charges as soon as they appear.

Contact your card issuer immediately

The Consumer Financial Protection Bureau (CFPB) advises reporting the charge right away and opening a dispute through your issuer’s app or customer service line.

Submit a formal dispute within 60 days

To preserve protections under the Fair Credit Billing Act, you must send a billing error notice within 60 days of the statement that includes the charge.

Understand the investigation timeline

Card issuers must acknowledge your dispute within 30 days and resolve it within two billing cycles, typically no more than 90 days.

Confirm the charge details before disputing

Check the merchant name, date and amount, since some transactions may appear under payment processors or parent companies.

Replace or block the card if needed

If the charge is unauthorized, the issuer can cancel the card and issue a replacement to stop further transactions.

Simply keeping an eye on your accounts may not be enough

Even if you check your statements regularly, small charges can still slip through and delay detection.

Timing can work against you

A lot hinges on when you check your account. If you review transactions infrequently or rely on monthly statements, unauthorized charges may only surface after they’ve already posted. By then, multiple transactions can appear across different dates or merchant names, making them harder to spot.

Alerts don’t always catch small charges

Notifications are not always consistent across accounts. Some banks alert you only after a transaction is completed, while others set thresholds that don’t flag low-dollar amounts. That can allow small charges to slip through without notice. If the same payment details are used elsewhere, activity may not appear in one place.

Ways to protect yourself from ghost tapping

These simple steps can help reduce your risk and catch suspicious charges before they turn into bigger fraud.

1) Turn on transaction alerts

Set up real-time alerts for all charges, even small ones, so you can spot suspicious activity immediately.

2) Use mobile wallets when possible

Apple Pay and Google Pay use tokenization, which means your real card number is not shared with merchants.

3) Keep your card secure in crowded places

Contactless cards can be read at close range, so avoid leaving them exposed in busy environments.

4) Check your accounts more frequently

Do not rely on monthly statements. Review transactions every few days to catch issues early.

How broader monitoring can help

Even with these steps, some suspicious activity may not show up in one place or right away. That’s where broader monitoring comes in. Identity and credit monitoring services are designed to track changes tied to your financial and personal information as they happen. This can include transaction monitoring along with three-bureau credit monitoring, so activity linked to your identity can be seen across accounts and credit files at the same time. That includes new inquiries, account openings and changes that would not appear in any one banking app.

Some services also scan known data breach records and dark web marketplaces for exposed personal information. If your data appears in those sources, you can receive an alert tied to the specific identifier that was found.

HOW DEBIT CARD FRAUD CAN HAPPEN WITHOUT USING THE CARD

If suspicious activity is detected, many platforms offer tools to take action quickly. This may include locking your credit file and working with a U.S.-based fraud resolution team to contact card issuers, dispute charges and close affected accounts.

Some identity protection services also include insurance coverage, often up to $1 million per adult, to help cover eligible losses and legal fees, along with 24/7 fraud resolution support to help restore your identity.

No service can prevent every kind of identity theft. If it happens, monitoring and guided support can make recovery easier to manage.

How to check if your personal information was exposed

If you are unsure whether your personal information has already been exposed, take action now. Our No. 1 identity theft protection pick includes a free identity breach scan, which allows you to see whether your data appears in known leaks. Early detection gives you more control and helps you respond before fraud spreads.

Kurt’s key takeaways

A small charge is easy to ignore, especially when it blends in with everyday purchases. But as these reports show, that’s exactly what scammers are counting on. A few dollars can be the first sign that your payment details are active and vulnerable, giving attackers a way to test and expand access without raising alarms. 

The sooner you catch it, the easier it is to stop. This is one of those situations where habits matter. Checking your transactions regularly, acting quickly on anything unfamiliar and adding an extra layer of monitoring can make a real difference. Fraud doesn’t always start big, but it often starts small.

Nothing cancels this year’s CMF phone due to RAM prices

Nothing cancels this year’s CMF phone due to RAM prices

Nothing’s next budget phone is the latest victim of RAMageddon. As 9to5Google reports, Nothing co-founder Akis Evangelidis announced in a post on X that a follow-up to the CMF Phone 2 Pro won’t be coming this year:

We were working on a successor but with memory prices where they are right now, we can’t build a phone that feels like a genuine step forward at a price that makes sense for CMF. As a result, we’ve decided not to launch a new CMF phone this year.

Last week, Nothing CEO and co-founder Carl Pei also said the RAM shortage has impacted the cost of the company’s mid-range phone, stating, “For Phone 4A, memory costs doubled between when we decided to build the device and when it launched. They’ve doubled again since.” According to Pei, “memory is now the most expensive component in a smartphone.” Nothing is far from the only company facing RAM pricing challenges — earlier this week, Tim Cook announced Apple will be raising prices, saying “the situation has become unsustainable.”

While there won’t be a new CMF phone this year, Evangelidis added in his post that CMF still has “several new products launching as well as some entirely new categories.” He also hinted that “the smartphone launch season at Nothing isn’t over yet.”

China’s brain chip breakthrough raises big questions

China’s brain chip breakthrough raises big questions

NEWYou can now listen to Fox News articles!

A coin-sized brain chip in China could help people with paralysis control devices using their thoughts. China has approved a brain-computer interface called NEO for commercial medical use in certain patients with paralysis caused by spinal cord injuries. That moves brain-chip technology out of research trials and closer to real-world medical care.

Developed by researchers at Tsinghua University and Shanghai-based Neuracle Technology, NEO sits under the skull but rests on the brain’s protective outer layer rather than piercing deep into brain tissue. That design could make it less invasive than some competing implants.

For patients who have lost movement, this kind of technology could be life-changing. It could help restore a level of independence that once felt out of reach. But here’s where we need to slow down a bit. If a brain chip can turn your brain signals into digital commands, we need to ask who controls that data and how well it is protected.

BRAIN IMPLANT ENABLES ALS PATIENT TO COMMUNICATE USING AI

What is China’s NEO brain chip?

NEO is a brain-computer interface, often called a BCI. These systems read brain activity and translate it into commands for an external device. In this case, the implant uses sensors placed near the brain’s motor-control area. Those signals can help a patient operate equipment such as a robotic glove or computer interface.

What makes NEO especially notable is its placement. Brain-computer interfaces can be designed in different ways, and some go deeper into the brain than others. The company most people know in this space is Neuralink, the brain-chip startup co-founded by Elon Musk. Its implant uses tiny threads that enter the brain’s cortex. NEO takes a less invasive approach by placing electrodes on the dura mater, which is the protective membrane around the brain.

That design matters because every brain implant carries medical risk. Surgery can cause bleeding, swelling, infection or tissue damage. Even a small complication in the wrong part of the brain can affect speech or movement.

China’s approval does not mean brain chips are suddenly available for anyone who wants one. This remains a medical device for a narrow group of patients. Right now, the focus centers on helping people with severe paralysis regain some digital or assisted movement control.

Why China’s brain chip breakthrough matters

The medical upside here is hard to deny. More than three billion people worldwide live with neurological conditions, according to the World Health Organization. That includes people dealing with stroke, epilepsy, Parkinson’s disease, spinal cord injuries and other serious conditions.

For someone who has spent years unable to move freely or communicate easily, even a small amount of restored control could feel enormous. That is why brain-computer interfaces are getting so much attention. They could give some patients a new way to interact with the world around them.

Neuralink has already shown what that can look like in real life. Audrey Crews, a Neuralink trial participant who has been paralyzed for years, publicly shared that she wrote her name using the implant by controlling her computer.

How China’s brain chip compares with Neuralink

Elon Musk’s Neuralink has attracted most of the public attention in the U.S. brain-chip race. Musk has talked openly about restoring movement, helping people communicate and one day addressing vision loss.

Neuralink received approval to begin human trials, and more than 20 people have reportedly received its implant through testing. However, it has not received broad FDA approval for general commercial use.

China’s NEO approval puts a different kind of pressure on the field. It shows that China wants to move brain-computer interface technology into its health system and build a major industry around it.

This also fits a larger pattern. China has made BCI development part of its strategic technology push. The country wants breakthroughs by 2027 and a globally competitive brain-computer interface industry by 2030.

Why brain chip privacy is such a big concern

We already worry about phones listening, apps tracking location and smart TVs collecting viewing habits. Brain-computer interfaces take that concern to another level.

A BCI collects signals from the nervous system. Today, that may mean decoding movement intent, such as whether a patient wants to move a cursor left or right. But as the technology improves, the data could become more sensitive.

That raises some big questions. Who owns the brain data? Can it be sold, shared or used to train AI systems? Could an insurer, employer or government ever demand access? What happens if a company changes its privacy policy after the implant becomes part of someone’s daily life?

Those questions sound dramatic until you remember how many connected devices began as conveniences and turned into data pipelines.

A brain chip designed for medical help should not become another ad platform, another surveillance tool or another database waiting to be breached.

YOUR HEALTH DATA IS BEING SOLD WITHOUT YOUR CONSENT

Could hackers target brain-computer interfaces?

This is where the whole brain-chip conversation gets very serious. Any device that connects to a computer raises security questions. A brain-computer interface raises even bigger ones because it deals with signals from your body and, in some cases, the devices that help you move or communicate.

The concern here is someone getting access to neural data, device settings or the commands moving between the implant and outside equipment. Think about that for a second. If a brain chip helps someone control a robotic hand, a wheelchair or a communication device, a security failure could affect far more than privacy. It could affect that person’s independence and safety. That to me is scary.

Companies building these devices need to treat cybersecurity like part of the surgery, not some software update they figure out later. Encryption, strict access controls, medical-grade testing and clear update policies should be baked in from day one.

And because a brain implant may stay inside a person’s body for years, long-term support has to be part of the deal. No one should end up with an outdated implant in their head because a company moved on to the next big product launch.

What China’s brain chip means to you

For now, this technology is geared toward patients with serious medical needs. So, no, most of us are not lining up for a brain chip anytime soon. But this should still get your attention.

We already give up a lot of personal data through our phones, watches, cars and smart home devices. A brain implant takes that to a whole different level because the data comes from inside the body. That is about as personal as it gets.

Before this technology moves beyond hospitals and medical trials, patients need plain answers before they agree to anything. They should know who can access the data, how long it gets stored, whether it can be shared and whether it can help train AI systems.

The medical potential here is incredible. Helping someone regain control or communicate again could change a life. But the privacy protections need to be just as strong as the technology itself.

Kurt’s key takeaways

China’s NEO brain chip could be a huge step forward for people living with paralysis. If this technology helps someone regain control or communicate again, that is powerful. But I also think we need to be very careful here. Once a device connects your brain signals to outside technology, the privacy stakes change fast. We are talking about data tied to your nervous system. That to me is the line we need to watch closely. Brain chips could do incredible good. But companies and governments need clear limits before this technology moves any further into everyday life. The promise is real. So are the risks. And when the data comes from inside your own head, “trust us” will never be enough.

NASA selects Eric Schmidt’s rocket company for a 2028 mission to Mars

Relativity Space, the rocket company led by former Google executive Eric Schmidt, was picked to launch NASA’s Aeolus payload to Mars in 2028, as reported earlier by TechCrunch. Under a new public-private partnership, Relativity Space will provide the “spacecraft, rocket, and cruise operations” to fly Aeolus to Mars, where the payload will “provide the first integrated, daily, global view of Martian winds, temperatures, dust, and clouds.”

The Aeolus payload will have four instruments on board for studying the Martian atmosphere, which NASA says will “directly inform entry, descent, and landing systems and support safer, more predictable mission planning for astronauts.”

Schmidt, who served as CEO of Google from 2001 to 2011, became Relativity Space’s CEO in 2025, a couple of years after it launched the “world’s first 3D-printed rocket,” Terran 1, which failed shortly after launch. Relativity Space’s larger Terran R rocket isn’t scheduled to have its first launch until later this year.
