Leave your COVID vaccine card at home: 8 safe ways to store it on your phone
You may need to show proof you are vaccinated to enter many restaurants, gyms and event venues or even the office, as the delta variant spreads. Here’s how to keep your vaccine information handy while leaving the paper card back at home.
With new vaccine mandates that span government workers and school districts to larger employers, the need to keep your COVID-19 vaccine card handy becomes more and more important. That goes for kids, too, who shortly may be eligible for the vaccine.
And it’s not just at the federal level. Cities and counties across the country are requiring proof of vaccination to attend live indoor events and enter gyms, restaurants and bars.
The vaccines continue to be highly effective in preventing hospitalization. Over the summer, as the delta variant spread across the US, the number of COVID-19 cases, hospitalizations and deaths climbed. Unvaccinated people have accounted for nearly all the hospitalizations and deaths — over 97% as of July. With the federal mandates, the Biden administration aims to stem the surge and put pressure on those who are eligible but not yet vaccinated.
That rectangular paper card you received when you were vaccinated will suffice to prove that you’re vaccinated. (And if there’s still room on the card, it can show you got a booster shot from Pfizer, Moderna or Johnson & Johnson when those are available.)
But what if you lose it, or it’s damaged or stolen? The Centers for Disease Control and Prevention doesn’t have a record of your vaccination status. We do know how to get a new vaccine card if yours is lost or damaged.
Rather than carrying around the card — or laminating it, which prevents your health care provider from updating it with future booster shots — take a few minutes to add a digital copy of your vaccination card to your phone. Here are a few options I’ve found while researching how to safely store mine.
There isn’t one approved way to show proof of your vaccination card
The US doesn’t have a single online system or app you can use to show proof of vaccination on your phone. Instead, what qualifies as proof varies by city, county and even business. Some places may accept a picture of your vaccination card; others may require you to use an app that’s authorized at state level.
It’s a confusing mess, to put it mildly. I strongly urge you to take a few minutes to research what your city, county or state will accept as proof, as it can vary.
For example, concert producer AEG Presents will accept a «physical copy of a COVID-19 Vaccination Record Card, a digital copy of such card or such other proof as is permitted locally.»
Along with school mandates, many colleges are are also requiring students and employees to be vaccinated. Seattle University, for example, requires students to be vaccinated to attend in-person classes via an online form that uploads photos of the front and back of the vaccination card.
When in doubt, look for information on the business’s website, or call the local health department and ask for clarification. This is bound to save you time, headaches and being turned away at the door.
Have an iPhone or an Android phone? Here’s an easy way to save your card
If you have an iPhone, with an update coming soon for iOS 15 you’ll be able to add your vaccine card to your Apple Wallet to present to whenever you need to show you’re fully vaccinated. (You can keep a copy in the Health app right now.)
Over on Android, you can add your vaccine card to the Google Pay app. I need to remind myself each time where my card is in Google Pay, so I added a shortcut icon to my home screen to quickly find it.
Own a Samsung phone? There’s an app just for you
Samsung now gives Galaxy phone owners the option to add proof of vaccination to Samsung Pay,its wallet app. By having direct access to your vaccination record, youwon’t have to fiddle around with creating photo albums and tappingthrough multiple screens before you’re able to show it to a bouncer atyour local watering hole.
To add your card to Samsung Pay, you’ll need to download the CommonHealth app(Samsung’s partner) from the Google Play Store. Follow the prompts inthe app to verify your vaccination status. Once the app confirms you’veindeed gotten the shots, you’ll be prompted to download a Smart HealthCard to Samsung Pay.
That card is what you’ll then show to anyone requesting you show proof of vaccination.
Use your phone to take a clear photo of your card
Is that too much fuss? The simplest way to have a digital record of your vaccine status is to snap a picture of your vaccination card and keep it on your phone. The CDC even recommends keeping a picture of your card as a backup copy.
Simply use the camera app on your phone to snap the photo. You can favorite the photo to quickly locate it or store it in a notes app, a folder or somewhere that’s easy to remember so you don’t have to endlessly scroll your camera roll to find it. Make sure you’re in a well-lit area and get close enough to the card that its dates and details are legible. I also suggest putting the card on a dark surface, while remaining conscious of shadows of your arms or the phone on the card itself.
Here’s an example of one way to save your vaccination card as a new photo album. On an iPhone, open the Photos app, select the Albums tab and then tap the + sign in the top left corner followed by New Album. Give the album a name and then tap Save. Next, select the photos of your card to add it to the album.
On an Android phone, it depends on which app you’re using, but the process should generally be the same. If you’re using the Google Photos app, open the app and then select the picture of your vaccination card. Tap the three-dot menu button in the top-right corner, followed by the Add to Album button. Select +New album and give it a name such as «Vaccination Card» and tap the checkmark button when you’re done.
Excelsior and more: Look for apps based on your location
Some states — including California, Colorado, Hawaii, New York and Oregon — offer some form of digital vaccination card. The myColorado app requires you to create an account, verify your identity and then add your digital driver’s license to your phone. After you’ve done that, you can then add your myVaccine record to the app.
Louisiana’s LA Wallet app takes a similar approach to Colorado’s, allowing you to add your driver’s license and proof of vaccination to your phone.
California’s implementation requires you to fill out a form to verify your identity, after which you’ll receive a text message or email with a link to a QR code you can save to your phone. When scanned, the code will offer proof of vaccination. The link will also include a digital copy of your vaccination record.
MyIR Mobile is another app used by several state health departments to provide a digital copy of your vaccination card. Currently, if you live in Louisiana, Maryland, Mississippi, North Dakota, Washington, West Virginia or Washington, DC, this is the app you’ll use.
More options to create and store your digital vaccination card
I’ve had a large number of readers reach out to me about this article, each one offering advice and guidance about storing a proof of vaccination card.
Some suggestions include well-known airport security service Clear. In fact, some concert and exhibition halls are requiring attendees use Clear to verify their vaccination status to attend a show. You can go to clearme.com/healthpass to download the app and get your card added.
VaxYes is another service that verifies your vaccination status and then adds your vaccination card to Apple Wallet. I’ve read that you can add your card to the Google Pay app, but after signing up and going through the process myself, I don’t see the option on a Pixel 5 running Android 12.
If your local municipality or employer used the CDC’s Vaccine Administration Management System, then you can use the VAMS website to access your vaccination records. I had more than one reader reach out to me about using this system to show proof of vaccination, but without an account myself, I’m unable to go through the process of accessing a vaccination record.
Another suggestion I received from multiple readers is to use a scanner app on your phone and store a scanned copy of your vaccination card in something like your OneDrive personal vault or a password manager (almost all of them offer some sort of secure file storage) instead of storing the photo in Google Photos or Apple’s iCloud photos. On an iPhone, you can use the scanner that’s built into the Notes app. On Android, Google’s Stack PDF scanner will be enough to get the job done.
This story updates as the national vaccine conversation continues. For more information about the forthcoming booster shots, make sure to read this. We have up-to-date details about the delta variant, as well as delta plus and the lambda variant.

Nvidia Expands AI Investment Strategy, Surpassing $40 Billion in Equity Commitments This Year
Nvidia’s equity investments have surpassed $40 billion this year as the chipmaker expands its financial footprint across the AI supply chain, raising questions about market sustainability and circular investment strategies.
Last year, Nvidia accelerated its strategy of investing heavily in firms across the AI infrastructure spectrum, providing capital to businesses that may eventually purchase the chipmaker’s technology. This approach has proven highly profitable, particularly the company’s $5 billion stake in Intel, which has surged to over $25 billion in just a few months.
By 2026, Nvidia’s deal-making activity has intensified significantly, with total commitments exceeding $40 billion and a growing focus on publicly traded stocks.
Earlier this week, Nvidia announced a $2.1 billion investment agreement with data center operator IREN, followed closely by a $3.2 billion pact with Corning, a century-old glass manufacturer. Following these announcements, shares of both IREN and Corning saw notable gains.
Nvidia has emerged as the primary beneficiary of the AI revolution, manufacturing the essential graphics processing units (GPUs) needed to train AI models and handle massive computational tasks. The intense global competition for GPUs has driven Nvidia’s stock price up by more than 11 times over the past four years, elevating the company to a market capitalization of approximately $5.2 trillion and making it the world’s most valuable enterprise.
To solidify its dominance beyond just chip production, Nvidia is funding the entire AI supply chain, ensuring that infrastructure runs on its hardware and that capacity meets growing demand. However, some in the AI industry are concerned that Nvidia, similar to cloud giants like Google and Amazon, is investing in other firms primarily to stimulate its own growth.
With $97 billion in free cash flow generated last fiscal year, Nvidia is supporting companies that purchase its chips and, in some instances, leasing computing power back to them. Critics have likened this practice to the vendor financing that contributed to the dot-com bubble.
Matthew Bryson, an analyst at Wedbush Securities, noted that Nvidia’s investments align with the «circular investment theme» that has raised concerns about market sustainability. Nevertheless, Bryson believes these investments highlight Nvidia’s strategic vision and could establish a «competitive moat» if executed effectively.
An Nvidia spokesperson did not respond to requests for comment.
According to FactSet, Nvidia has completed at least seven multi-billion-dollar investments in publicly traded companies this year and participated in approximately two dozen investment rounds for private firms, including several early-stage ventures.
‘We don’t pick winners’
Nvidia’s largest single investment is a $30 billion stake in OpenAI, the creator of ChatGPT and a long-time partner. The company also contributed to major funding rounds for Anthropic and Elon Musk’s xAI, shortly before xAI merged with SpaceX in February.
«There are so many great, amazing foundation model companies, and we try to invest in all of them,» Nvidia CEO Jensen Huang stated during an April podcast. «We don’t pick winners. We need to support everyone.»
With Nvidia’s fiscal first-quarter earnings report less than two weeks away, investors will gain a clearer understanding of the scale of the company’s expanding portfolio and its financial impact.
During the previous fiscal year, Nvidia invested $17.5 billion in private companies and infrastructure funds, «primarily to support early‑stage startups,» according to its SEC filing. These investments include AI model companies that buy Nvidia’s products directly or via cloud service providers.
Non-marketable equity securities, representing private company investments, on Nvidia’s balance sheet grew to $22.25 billion by the end of January, up from $3.39 billion a year prior. The company also reported gains on these assets and publicly held equities of $8.92 billion, up from $1.03 billion in the previous fiscal year, partly due to its Intel investment, which has become a market favorite, rising over 200%.
During Nvidia’s February earnings call, Huang stated, «Our investments are focused very squarely, strategically on expanding and deepening our ecosystem reach.»
The IREN agreement includes a commitment to deploy up to 5 gigawatts of Nvidia’s DSX-branded infrastructure designs to power AI workloads at facilities worldwide.
Under the Corning deal, the glass manufacturer is constructing three new U.S. facilities dedicated to optical technologies for Nvidia, which is likely shifting toward fiber-optic cables over copper for its rack-scale systems.
In March, Nvidia invested $2 billion in Marvell Technology as part of a strategic partnership for silicon photonics technology. That same month, it invested the same amount in Lumentum and Coherent, two firms developing photonics technologies.
Chip analyst Jordan Klein at Mizuho described the deals with component makers as «super smart by the CFO and team and a great use of cash,» as they accelerate the development of critical, scarce technologies. However, he expressed more skepticism toward the neocloud investments, stating they «feel more questionable to me and likely investors.»
«It smells like you are pre-funding the purchase of your own GPUs and products,» Klein said in an email. Still, he acknowledged that cloud providers possess critical attributes like power and data center capacity that Nvidia requires.
Ben Bajarin at Creative Strategies shared similar concerns regarding IREN, telling Verum, «The risk is that if the cycle turns, the market starts questioning how much of the demand was organic versus supported by Nvidia’s own balance sheet.»
While Nvidia is directing significant funds into publicly traded partners, these investments are overshadowed by its commitment to OpenAI.
Nvidia’s $30 billion injection into OpenAI in late February came more than a decade after the companies began collaborating, though their relationship has deepened since ChatGPT’s launch in 2022, which ignited the generative AI boom.
Nvidia’s initial investment in OpenAI was intended to be much larger. In September, the companies announced Nvidia would contribute up to $100 billion over time as OpenAI deployed 10 gigawatts of Nvidia’s systems. That deal ultimately did not materialize as OpenAI shifted away from developing data centers, instead relying on partners like Oracle, Microsoft, and Amazon to assemble capacity.
Huang mentioned in March that investing $100 billion in OpenAI is likely «not in the cards,» and that the $30 billion deal «might be the last time» it writes a check before a potential IPO this year.

Why Privacy Begins Where Even the Service Creator Can’t See Anything
Why Privacy Begins Where Even the Service Creator Can’t See Anything
Today, almost every messenger promises “security” and “encryption.” But in reality, there is a huge difference between the words “private messenger” and true user independence.
Most modern platforms are still built around trust in the company. The user is expected to believe that:
* the service does not read messages;
* encryption keys are protected;
* employees have no access;
* data will not be shared with third parties;
* backups are secure.
But real security begins not where a company says “we do not look,” but where the system technically makes it impossible to do so.
This is exactly the principle behind Verum Messenger.
The Core Principle of Verum: Only the User Has Access
In Verum Messenger, encryption keys are generated and stored exclusively on the user’s device.
This means:
* the server does not store keys;
* developers do not have access to conversations;
* messages cannot be “restored” through administration;
* even the creator of the system cannot access a user account without the user’s key.
The key belongs only to the owner.
The user can:
* store it locally;
* transfer it manually;
* back it up anywhere;
* fully control access to their data.
The system is not built around trust in a company. It is built around eliminating the need to trust anyone at all.
Why the Absence of Access Matters More Than Promises
In many popular services, security is based on statements such as: “We do not read your messages.”
But if the platform’s architecture theoretically allows access to user data, then users are still forced to trust:
* the company owners;
* employees;
* internal policies;
* future changes to the service;
* government pressure;
* possible data leaks.
Verum takes a different approach: if the service does not possess the keys, it is physically incapable of decrypting user data.
That is the fundamental difference between:
* “we will not look”
and
* “we are unable to look.”
Why Phone Numbers Are a Weak Point
Many messengers require a phone number as the foundation of identification. But a phone number is not just a registration method.
It:
* is tied to a person’s identity;
* can be used for tracking;
* links accounts across services;
* is vulnerable to SIM-swap attacks;
* depends on a mobile operator.
Verum removes this dependency.
Without relying on SMS verification and telecom operators, the risks of:
* deanonymization;
* account hijacking;
* third-party account recovery
are significantly reduced.
Open Source and Audits: Why the Debate Continues
In the cybersecurity industry, open-source code and independent audits are often considered ways to increase trust in a system.
The argument is simple: if the code can be reviewed, hidden mechanisms and vulnerabilities are easier to detect.
But there is another perspective.
Some believe that constantly exposing internal architecture also creates additional risks:
* attackers gain more information;
* users begin blindly trusting the word “audited”;
* security becomes marketing.
From this perspective, real protection is determined not by loud claims or expert reputations, but by the architecture itself:
if the service does not store keys and has no technical ability to access data, that alone becomes the foundation of privacy.
Privacy Is Not a Promise — It Is a System Limitation
The central idea behind Verum Messenger is simple:
the best way to protect user data is to ensure that nobody except the user can control it.
Even the platform owner.
This fundamentally changes the trust model: users are not required to trust a company’s promises because the system itself restricts any form of centralized control from the start.
In this approach, privacy stops being a feature.
It becomes an architectural principle.
