I recently moved, and for a few days, in between moving out of one place and into the other, I didn’t have anywhere to stay. So I checked into a hotel, a place I usually associate with plastic key cards, front desk pens chained to the counter and paper receipts you fold into your wallet and forget about.

But when I checked in, the only thing they asked for was my ID. Everything else happened through my phone. I used my credit card via Apple Pay to put down the deposit and pay for the room. The hotel concierge recommended I add my room key to Apple Wallet, so that I can tap my phone to enter my room. I was also provided with a food and beverage credit — in the form of a QR code that the in-hotel restaurant could scan. The receipt was emailed to me.

The next day, I went to U-Haul, another place I expected paperwork, clipboards and a long conversation at a counter. Instead, I checked in on my phone, got a code, grabbed the key from a lock box and took the truck. I had uploaded my ID to the app a while back, and it used that along with a face scan to verify who I was. I picked up the moving truck without dealing with anyone in person, and without ever taking out my wallet.

A few days later, as I moved my things into my new apartment, the landlord asked whether I had signed up for online payments. «You can pay rent through an app now,» he chuckled. I nodded, as if it were commonplace. I’m old enough to remember carrying a checkbook, or at least a few checks in your wallet, to pay for rent.

Somewhere over the past few years, without really planning it, my phone had quietly taken over almost everything my wallet used to do. I just didn’t really notice when it happened.

Many of the physical things we used to carry every day have slowly disappeared into our phones. Maps, cameras, boarding passes, tickets, keys and now wallets all live inside one single device. 

That shift happened too gradually for me to notice, but it’s changed how we move through the world. We’ve gained convenience, but we’ve also made one device responsible for almost everything in our lives.

How did we get here?

I still remember when my wallet was packed full of stuff: cash, coins, receipts, business cards and random scraps of paper I thought I might need later. The slim card holder I carry now pales in comparison to the massive George Costanza-esque wallet I had in college.

Around that time, in 2008, I got my first iPhone, and I didn’t really think about what it would eventually replace. It was mostly a phone, a portable music player and a way to look at the internet without sitting at a computer. You still had to print boarding passes. You still carried a debit card everywhere. You still needed cash.

Then, one by one, things started moving onto my phone. Google Maps replaced printed directions from MapQuest. Tickets for concerts and movies became QR codes that could be scanned at the venue. Boarding passes moved into airline apps. Ride-share apps replaced taxis and the need to carry cash to get around the city.

In 2014, Apple Pay launched in the US. At first, it felt like a novelty. Only a few places accepted it, so you still needed your wallet for the most part. But over time, more terminals started accepting Apple Pay and other tap-to-pay services like Google Pay and Samsung Pay. Eventually, more of my debit and credit cards migrated to my digital wallet, until tapping my phone, or even my smart watch, became completely normal. 

Juniper Research projected in 2022 that more than 60% of the world would be using digital wallets by this year. Last year, the US Federal Reserve reported that 23% of US payments in 2024 were handled via phone, and for people aged 18 to 24, that number jumped to 45%. In the last few days, I used Apple Pay over a dozen times, and that’s just counting my main debit card, and not all the various credit cards I have to get points on groceries and travel.

For most of my life, the worst thing that could happen when leaving the house was forgetting my wallet. No ID, no money, no cards — you couldn’t do anything. Now, that’s no longer the case. 

Convenience is great until you lose your phone

On the surface, the convenience is appealing. Not having to carry cash, not having to dig through your wallet for the right card, not having to keep track of paper tickets or boarding passes. It’s pretty nice, actually. Everything is faster, easier and more streamlined with your phone. 

In a lot of ways, it’s also more secure. Mobile wallets like Apple Pay and Google Pay don’t store your actual card number. Instead, they use tokenization, generating a unique code for each transaction so your real card details are never shared. And there’s also biometric authentication, like Face ID or fingerprints, so tapping your phone is generally safer than handing over a physical card.

But the trade-off isn’t really about security. It’s about concentration.

Not that long ago, the things in your wallet were separate. If you lost your movie ticket, you could buy another. If you lost your plane ticket, you could go to the airline counter and get it reprinted. If you lost your credit card, you still had cash.

Now almost everything lives in one place. And so losing your phone isn’t losing one thing. It’s losing access to everything.

And phones get lost and stolen all the time. In 2024 alone, about 7.3 million were lost or stolen in the US, according to Asurion claims data, and most are never recovered.

To reiterate, losing a phone today isn’t just losing a device. It can mean temporarily losing access to your bank accounts, your email, your photos, your tickets, your digital ID and sometimes even your apartment or car. Even recovering your accounts can be complicated. Two-factor authentication codes are often sent to your phone, which means the thing you need to regain access to your accounts is the same thing you just lost.

And if someone can unlock your phone, they could have access to your entire digital life.

At the same time, identity theft and online fraud are rising. The FBI reported that Americans lost more than $16 billion to internet-related crimes in 2024, while the Federal Trade Commission says millions of fraud and identity theft reports are filed every year. 

Not all of those crimes come from stolen phones, but the more our identities, payments and accounts live on our phones, the more valuable those phones become. Not just as devices, but as keys to everything else.

If you lose your phone, you might be stuck with no map, no way to pay, no way to get home, no way to prove who you are and no easy way to get back into your accounts.

And to think, losing a wallet used to be a bad day.

What comes next?

If the phone replaced the wallet, the next question is what replaces the phone? In some places, that shift has already started.

At newer venues like the Intuit Dome, you can enter, buy food or grab a beer without pulling anything out of your pocket. Systems like Amazon One use your palm (although it’s being phased out), while others use face scans tied to your account. Airports and retailers are experimenting with similar setups: You walk in, you’re identified, and you’re charged without tapping a card or even a phone.

In theory, biometrics can be more secure. You can’t forget your face or your fingerprint at home, and these systems still rely on the same underlying protections: tokenization, encrypted credentials and account-level authentication.

But they introduce a different set of risks. Unlike a password or a credit card number, your biometric data can’t be changed if it’s compromised. These systems also rely on centralized accounts and databases, which means you’re trusting companies not just with your money, but with your identity. And they don’t always work perfectly: Lighting, cameras, network issues or simple glitches can still get in the way.

During a Clippers game at Intuit Dome, facial recognition stopped working at one of the restaurants, and I was privately told by management that I could grab as much food and alcohol as I wanted without being charged. Oops.

It also changes something more subtle. The transaction disappears entirely. There’s no moment where you decide to pay — you just walk in, pick something up and leave. Without that pause, spending feels less like a conscious choice and more like you’re just going through the motions. At some point, you stop keeping track.

The wallet turned into the phone, and now the phone is starting to disappear, too.

My wallet isn’t dead to me… yet

I do still carry a wallet. It’s a backup to my phone, and something that doesn’t have a battery that can die and leave me stranded. It just doesn’t come with me everywhere anymore.

Most days, I leave the house with just my phone and don’t think twice about it. It’s easier. It’s faster. It works.

And I don’t think I’d go back.

But there are moments when I miss what the wallet used to be. The physical stuff. The receipts, the ticket stubs, the random things that built up over time. The proof that you had been somewhere, done something, met someone.

Now most of that is gone. Or at least, it doesn’t exist in the same way. It lives somewhere in an app, an email or a cloud backup I’ll probably never open again.

I do like the convenience. I like not having to think about it. But I also know I’m carrying something very different now. It’s not just a phone. It’s access to my money, my identity, my tickets, my way through the world.

And more and more, it feels like the one thing I can’t afford to lose.
