The Youths Have Spoken: Wallets Are Uncool. Go Digital.

By Brian X. Chen and Yiwen Lu

To a growing number of youths, a wallet stuffed with cash and cards is as unfashionable as the millennial tuck, no-show socks and skinny jeans. Carrying only a smartphone is the way. Iykyk — that’s “if you know, you know,” for those who don’t know.

I, Brian Chen, a graying 39-year-old tech columnist, am not one of those in the know. It’s unfathomable to me to part with my wallet, which holds crucial items like my driver’s license. So in an effort to be hip again, I recruited my 23-year-old colleague Yiwen Lu to ask the young ones how they live like this, and then I took the jump myself.

In ditching my physical wallet, I am joining youths like Ruby Hegab, a 19-year-old student in Fremont, Calif. As soon as she got her first credit card last year, she said, she went all-in on using her iPhone to pay for groceries, parking meters and restaurant meals, and for carrying insurance cards.

“If a store doesn’t accept Tap to Pay, I won’t give them business,” Ms. Hegab said. But that rarely happens, because the overwhelming majority of merchants she visits, including big box retailers and mom-and-pop shops, now accept some form of mobile payment from services like Apple Pay and Venmo.

In a survey asking just over 2,500 Americans about digital payments, some 80 percent of Gen Z respondents said they were using mobile wallets, and among them, half were eager to use their phones for much more than paying for things, according to recent data from Pymnts Intelligence, a research firm that studies commerce.

Younger people are increasingly using their phones for purposes that older adults would use a traditional wallet for, like carrying documents such as a driver’s license, boarding passes and event tickets. Some of these digital items can be added into the Apple and Google wallet apps, while others, like insurance cards, can be downloaded through third-party apps.

The shift in behavior is a reflection of how far mobile wallets have come. About a decade ago, when I covered emerging mobile payment apps, most people shrugged at the technology because tapping a phone on a scanner was no more convenient than swiping a credit card. In recent years, amid a global pandemic that drove people toward contact-free payments, Apple and Google expanded their software to support digitized driver’s licenses and transit cards, a perfect storm that made mobile wallets more useful.

Braving it without a wallet for a week, I used only my phone to do my shopping; go to bars, out for dinner and to the movies; and even buy crab from a fisherman’s boat. The phone sufficed in almost all those situations, though paying for dinner was more complicated and using a digital driver’s license to buy wine at a grocery store was a nonstarter.

If you’re hoping to ditch your wallet or simply want to cut down on some bulk in your pocket, here’s what you need to know.

Payments

In many stores, Android and iPhone users can use Google Pay and Apple Pay by tapping their phones on readers next to the cash register. Many small businesses such as food trucks accept payments through third-party apps like Venmo, which let you scan a bar code to send money.

Yet there is inherent risk when you rely fully on a mobile wallet. Abi Hoyer, 21, in Punta Gorda, Fla., said she didn’t carry a wallet for safety reasons: In the event of a mugging, a thief would get only her phone. Still, thieves could potentially make payments and drain money from your account if they coerced you into sharing your passcode.

That’s why it’s important for iPhone users to activate a new safety feature in settings called Stolen Device Protection, which prevents passcode access to data such as passwords and stored credit cards when the device is in an unfamiliar location. And Android users should be aware of the steps to lock and purge data from the device in the event of theft.

In addition, not all businesses take mobile payments. Ms. Hoyer learned this the hard way at Walmart when she discovered she was unable to pay for her items and didn’t have her full credit card number to sign up for the store’s wallet, Walmart Pay. One workaround: Password manager apps like 1Password and Bitwarden can safely store sensitive data including credit card numbers in case you need to look them up.

Jillian Gillespie, 27, in Chicago, switched to Apple Pay after losing her wallet over a year ago, she said. This works out fine for fast-casual restaurants where you pay at the counter, but at sit-down restaurants where waiters drop off a bill and expect to run a credit card, she occasionally has to rely on friends to pay. In those cases, she typically uses Venmo to reimburse her friends.

“I don’t really carry my wallet around with me, which sometimes can bite me in the butt,” Ms. Gillespie said.

I ran into similar snags. Out of three restaurants, only one brought a reader for me to tap my phone to pay, while the others asked for a credit card, which required my wife to pay.

Insurance cards and other documents

Digital scans or photos of important documents like health insurance and car insurance cards are now broadly accepted as substitutes for the real thing. Some insurance providers, like State Farm, Aetna and Anthem, make their digital cards available through their apps, which can be added to your mobile wallet. Not all insurance cards work this way, though, and it can be a hassle to find those cards at a moment’s notice — you don’t want to be stuck sifting through photos or finding the right app to load your insurance card after a car crash, for instance.

I found that the simplest method to make insurance cards easy to look up is to attach images of all of them to one digital note stored on your phone. On iPhones, you open your photo of the insurance card, tap the button in the lower left corner and select the Notes app to save the image to a new note. Then rename the note “Insurance Cards.”

Similarly, Android users can use the Google Keep note-taking app. In Keep, at the bottom tap “add image.” Then pick the photo of your insurance card and label the note.

Other types of cards and documents, like my Clipper card for public transit, movie tickets and gift cards, were all simple enough to digitize: Tapping the Add to Apple Wallet button loaded them inside my Apple wallet app.

Identification

Digitized versions of driver’s licenses are still relatively new and being tested in various states, including California, Arizona, Connecticut, Maryland and Utah. This is where the mobile wallet falls short.

Here in California, for example, you sign up for the digital driver’s license through the California Department of Motor Vehicles app. The app generates a temporary bar code that can be scanned to verify your age and identity. Airports in some states now display signs stating that they will accept the digital ID from those who have signed up for the Transportation Security Agency’s PreCheck program — but many states have yet to participate in this experiment, which makes it impractical to leave your driver’s license at home.

The digital ID is also not yet an acceptable substitute for a physical driver’s license. The California D.M.V. says law enforcement officers cannot accept the mobile driver’s license if you are pulled over, and Arizona’s Motor Vehicle Division says people are still required to carry a physical ID.

In the event of an emergency, a person may also have trouble identifying you. Apple’s Medical ID and Google’s Personal Safety features can be set up to show people your name, age and emergency contacts by pressing a shortcut on the phone — but emergency medical workers would have to know how to use the feature.

So it’s best to continue carrying a physical ID. To do that without carrying a wallet, you could do what some younger people do and sandwich the ID between your phone and phone case. I found that to be an imperfect solution because the card elevates the phone closer to the edges of the case, which makes the screen more susceptible to damage when it’s dropped.

After a week, I settled on what I felt was the best solution: a magnetic wallet that attaches to the back of my phone and carries only two cards — my ID and one credit card.

That felt like cheating. But Ms. Hegab, the 19-year-old, admits that she uses a similar card holder for carrying only her driver’s license.

As soon as digital driver’s licenses work everywhere, she said, she’ll be getting rid of it.

AI to Track Icebergs Adrift at Sea in Boon for Science

British scientists said Thursday that a world-first AI tool to catalogue and track icebergs as they break apart into smaller chunks could fill a "major blind spot" in predicting climate change.

Icebergs release enormous volumes of freshwater when they melt on the open water, affecting global climate patterns and altering ocean currents and ecosystems, reported AFP.

But scientists have long struggled to keep track of these floating behemoths once they break into thousands of smaller chunks, their fate and impact on the climate largely lost to the seas.

To fill in the gap, the British Antarctic Survey has developed an AI system that automatically identifies and names individual icebergs at birth and tracks their sometimes decades-long journey to a watery grave.

Using satellite images, the tool captures the distinct shape of icebergs as they break off -- or calve -- from glaciers and ice sheets on land.

As they disintegrate over time, the machine performs a giant puzzle problem, linking the smaller "child" fragments back to the "parent" and creating detailed family trees never before possible at this scale.

It represents a huge improvement on existing methods, where scientists pore over satellite images to visually identify and track only the largest icebergs one by one.

The AI system, which was tested using satellite observations over Greenland, provides "vital new information" for scientists and improves predictions about the future climate, said the British Antarctic Survey.

Knowing where these giant slabs of freshwater were melting into the ocean was especially crucial with ice loss expected to increase in a warming world, it added.

"What's exciting is that this finally gives us the observations we've been missing," Ben Evans, a machine learning expert at the British Antarctic Survey, said in a statement.

"We've gone from tracking a few famous icebergs to building full family trees. For the first time, we can see where each fragment came from, where it goes and why that matters for the climate."

This use of AI could also be adapted to aid safe passage for navigators through treacherous polar regions littered by icebergs.

Iceberg calving is a natural process. But scientists say the rate at which they were being lost from Antarctica is increasing, probably because of human-induced climate change.

AMD Predicts Weaker First-Quarter Sales, Shares Plunge on Nvidia Comparisons

Advanced Micro Devices on Tuesday forecast a slight decline in quarterly revenue, raising concerns about whether it ​can effectively challenge Nvidia in the booming AI market and sending its shares tumbling 8% in after-hours trade.

The lackluster prediction comes despite an unexpected boost from sales of certain artificial intelligence chips to China, which began in the last quarter after the Trump administration approved a license for orders that AMD received in early 2025.

And without those sales to China which generated $390 million, AMD's data-center segment would have missed estimates for the fourth quarter.

AMD said it expects revenue of about $9.8 billion this quarter, plus or minus $300 million. That's down from $10.27 billion in the fourth-quarter which was up 34% year-on-year and ahead of LSEG ‌estimates for $9.67 billion.

PALES ‌NEXT TO NVIDIA

Though AMD is seen as one of the ‌few ⁠contenders ​that can seriously ‌challenge Nvidia, investors noted the stark contrast between the two companies' performances. AMD expects an adjusted gross margin of 55% this quarter. Nvidia has said it expects adjusted gross margin in the mid-70% range during its fiscal 2027.

"The expectations for large blowout quarters for AI-related hardware companies have skewed what the market is looking for," said Bob O'Donnell, president of TECHnalysis Research.

The forecast for the current first quarter includes $100 million from sales to China, where the situation remains "dynamic," AMD CEO Lisa Su said on a conference call with investors.

The US government ⁠has placed restrictions on the exports of advanced chips to China, but AMD received licenses to sell modified versions of its MI300 series ‌of AI chips there. Its MI308 chip competes with Nvidia's H20 ‍chip in China.

OPENAI SALES

AMD has accelerated its ‍product launches and is moving into selling full AI systems to better compete against Nvidia, which now ‍provides "rack-scale" systems that combine GPUs, CPUs and networking gear.

Last year, it entered into a multi-year deal to supply AI chips to ChatGPT-owner OpenAI, which would bring in tens of billions of dollars in annual revenue and give the startup the option to buy up to roughly 10% of the chipmaker.

Su reiterated on Tuesday that the company ​expects sales of a new flagship AI server to OpenAI and others to rise rapidly in the second half of this year, saying a global memory-chip crunch will not ⁠slow its plans.

"I do not believe that we will be supply-limited in terms of the ramp that we put in place," Su said.

BEYOND OPENAI

As Big Tech and governments across the globe double down on investing in AI hardware, shares in Santa Clara, California-based AMD have doubled since the start of 2025, outperforming a 60% bump in the broader chip index.

But analysts remain concerned that AMD's success remains tied to a handful of customers that rivals such as Nvidia could try to poach. Reuters reported this week that Nvidia made a $20 billion move to hire most of chip startup Groq's founders after OpenAI held chip supply discussions with the startup.

"Growth appears concentrated in large deployments and specific regions, and China shipments are significant enough to influence a quarter," said eMarketer analyst Gadjo Sevilla.

Revenue in AMD's key data-center segment grew 39% to $5.38 billion in the ‌fourth quarter. But excluding sales of the MI308, which is a data-center chip, that revenue would have been $4.99 billion, below estimates of $5.07 billion.

Switch 2 Sales Boost Nintendo Results but Chip Shortage Looms

The runaway success of the Switch 2 console drove up Nintendo's net profit by more than 50 percent in the nine months to December, the Japanese video game giant said Tuesday.

But a global memory chip shortage, created by frenzied demand for artificial intelligence hardware, could push up manufacturing costs.

The Switch 2 became the world's fastest-selling games console after launching to a fan frenzy last summer.

It is the successor to the original Switch, which soared in popularity during the pandemic when games such as "Animal Crossing" struck a chord during long lockdowns.

Both are hybrid devices that can be connected to a TV or used on-the-go.

In April-December, net profit jumped 51.3 percent year-on-year to 358.9 billion yen ($2.3 billion), and revenue nearly doubled on-year to 1.9 trillion yen, Nintendo said.

But the firm kept its annual unit sales target for the Switch 2 steady at 19 million, and also held its full-year net profit forecast of 350 billion yen.

"Nintendo Switch 2 got off to a good start following its launch on June 5 and unit sales continued to grow through the holiday season," the company said.

Nearly 17.4 million Switch 2 devices were sold in the nine-month period, it added.

"Maintaining momentum is certainly a big focus for Nintendo," Krysta Yang of the Nintendo-focused Kit and Krysta Podcast told AFP.

A lack of heavy-hitting first-party new games for the Switch 2 in coming months risks hindering growth, although third-party titles such as "Resident Evil Requiem" should help fill the gap, she said.

Nintendo said Tuesday it planned to release "Mario Tennis Fever" this month and "Pokemon Pokopia" in March.

While the firm is diversifying into hit movies and theme parks, consoles remain the core of its business.

The Switch 1 has now sold 155.37 million units -- overtaking the Nintendo DS console to be its best-selling hardware of all time.

But soaring prices for memory chips, used in gaming consoles as well as phones, laptops and other electronics, will likely be a headwind for the company.

Their prices have been pushed up as chipmakers focus on producing the advanced memory chips in huge demand to power AI data centers.

"Nintendo and other console manufacturers are publicly keeping quiet about the impact of the shortage," gaming industry consultant Serkan Toto told AFP.

But "users can forget the past when consoles always became cheaper in tandem with component costs falling over time", with price hikes potentially on the way in 2026, he said.

Yang said she thought a price increase for the Switch 2 "is not out of the question" but added that Nintendo "would likely exhaust all other options" before doing so.
