A dear friend of mine who took care of my mom during her cancer journey and came over with his family for dinner last week. It was only when I was putting out plates that I realized I had no placemats or cloth napkins. (I’m sure they’re in some box in the garage.) So yesterday, I placed an order for new ones at Williams-Sonoma, and within five minutes, there were six other charges on my credit card from the site.

You see, I have my credit card set up to alert me when a purchase is made and my card isn’t present. While Williams-Sonoma is def not a sketchy site, the ordeal reminded me about the value of virtual cards. I don’t think I’ve explained these to you in some time.

A credit card you can switch off

Virtual cards use a randomized 16-digit number, a three-digit CVV code and an expiration date. You can sub in a virtual card for your typical online or in-store purchases. They connect to your real banking or credit accounts, but the retailers themselves can't see your actual card details.

That means an extra layer of protection against fraudsters. This is smart, sure, but you know what’s even smarter? You can easily turn off virtual cards for subscriptions without the hassle of canceling through the merchant (who wants you to keep paying).

Three virtual cards worth your time

If you’re lucky enough to have a credit card with a virtual number already built in, you’re set. If not, no problem — I found two other free options worth considering.

Best built-in: Capital One

Price: Free

A starter option: Revolut

Price: One card free, then $5 each for extra cards (or $10 per month for unlimited cards)

All the bells and whistles: Privacy

Price: Free for up to 12 cards per month ($10 per month for pro plans)

Always practice safe shopping

You don't need to be paranoid about shopping online; you just need to be smart. Read the complete list of card specs, plus extra tips for safe shopping, right here! (I couldn’t fit everything in the newsletter.)

😶‍🌫️ Ugh, I wish I could focus more when buying stuff online, but I keep checking out ...

Upgrade your phone pics (hello, better selfies and family pics!) with these attachments.

🦐 AI invasion: Facebook's algorithm is now pushing AI-generated content that goes straight to ad-heavy websites and scams. Some of these spam images look real, and others, like "Shrimp Jesus" (paywall link) are so weird that people can’t help but click. Meta's response? Crickets, as usual.

Stay tuned: YouTube star MrBeast just struck a deal with Amazon MGM for the biggest competition series in TV history. "Beast Games” is a reality show featuring 1,000 contestants duking it out for a $5 million prize. A thousand? I have enough trouble keeping the contestants on “The Bachelor” straight.

💼 Trending job skills: Remember when "data" was just a “Star Trek” character? Well, “data science” and “analytics” are now the hottest job categories, according to a 2024 study. The fastest-growing skills? Generative AI modeling, data analytics and machine learning. Share this with someone you know in college.

Work hard, play hard: LinkedIn's mixing business with pleasure with their new puzzle games. The angle? Play online games with your connections and contacts. Seems more like a recipe for distraction, but go ahead, dunk on your work frenemy.

👂 Tinnitus relief: That annoying ringing in your ears that just won't quit? Yeah, could be tinnitus. There’s no cure yet, but a new app called MindEar could offer some relief. It mixes chatbot tech, sound therapy, and mindfulness and meditation exercises to silence that high-pitched ringing. Get this: In its first trial with 30 participants, nearly two-thirds reported some improvement. Pretty awesome, right?

PSA for parents: Kids are using Apple's "invisible ink" in iMessage to send secret texts. This feature hides messages under a static effect called “dancing pixels” that disappear with a tap. You can disable it altogether under Settings > Accessibility > Reduce Motion.

🍔 Where’s the beef? Wendy’s “dynamic pricing” PR nightmare solution is $1 burgers until April 10 as a make-good. Of course, you have to order on their app and add the coupon on their “offers” page to get the deal. 🙄

Everything is pulse-ible: Nvidia is close to replacing some human nurses with AI, all for a mere $9 an hour. Yep, you read that right. These AI nurses will do things like guide you through colonoscopies, help manage your breast cancer care and, of course, keep your doc in the loop. Check out the video. With the current nursing shortage, this could def take off.

Your phone’s address book has all the juicy details on the people you care about — birthdays, pics, names, email addresses. Newsflash: That’s not your info to share.

Seems harmless, right? What does it matter if you let X or Meta dive into your contacts? Get this: From your address book, companies build “shadow profiles” for people who aren’t on their sites, just based on info they get from their friends who don’t realize how much they’re sharing.

The “what can I do?” is simple:

🛑 Pay attention, folks. Stop sharing info without a real benefit to you. It’ll make a world of difference for your privacy.

Make it math for you: The Calculator app in Windows isn't just for normal number crunching — it’s for life! Click the three lines in the top left to see everything else it can do, from converting currencies to calculating the number of days between two dates. You’ll know exactly how long you have until that next work deadline … or your anniversary.

One woman’s trash is another’s treasure: Don't shy away from putting older or broken tech on sale on sites like eBay. Plenty of people will take a chance on something they think they can fix or use the parts from, even if you've given up on it.

I'm making a list: It’s easy to save places in Google Maps, like that out-of-the-way coffee shop you love. With a pin selected, tap Save. Try making lists for trips or cities, and you can share them with your travel buddies, too.

🗑️ Delete means delete! The trash folder on macOS can be a lifesaver when you delete something accidentally, but what about you when you want it gone for good? Select a sensitive file in Finder, then hold down Option before selecting File and Delete Immediately — it’s gone.

Just brows(er)ing: The Camelizer for Chrome is a smart way to save money on your next Amazon purchase. When the price drops on something you want to buy, you'll get an alert.

I trust SimpliSafe to protect my home and studio from break-ins, fires, floods and any unwelcome surprises. With SimpliSafe, you don’t just get alerts on your phone — you get a fortress.

Not sure where to start? Take their quick quiz to see the perfect system tailored to your specific needs. Whether you live in a cozy apartment or a sprawling home, or you oversee a business, they’ve got you covered.

Between a rock and a hard place.
