QR Code Guide for Seniors: Easy Steps to Get Connected

I recently had a mind-blowing experience at a new taco joint in town.

My friend and I walked in, ready to stuff our faces with delicious, Mexican-inspired goodness. But instead of being handed a menu, we were directed to… the napkin holder!!!

At first, I thought, “Great, they already know I’m a messy eater.” But no, it wasn’t because of my inherent inability to keep food off my shirt.

Warning: QR Codes Aren’t Always Your Friend

While QR codes can be super convenient, they’re not all sunshine and helpful links. Some can be used to trick you.

In fact, scams with QR codes have been growing at an alarming rate.

Scanning the wrong code might send you to a shady website or even download something harmful onto your phone—and the worst part is, you won’t know it’s dangerous until after you’ve scanned it.

It’s kind of like opening a mystery package that shows up on your doorstep:

Sure, it could be something exciting, like that sequin pillow with your cat’s face on it. But it could also be something you want nothing to do with, like a giant glitter bomb that’ll take weeks to clean up.

That’s why it’s important to stay cautious. Just because a QR code is sitting there doesn’t mean you should scan it.

Always check where the code is coming from, and use a scanner that gives you a preview before taking you to a website (like the Trend Micro QR Scanner mentioned earlier).

It’s a quick way to avoid any unpleasant surprises—like glitter you’ll never get rid of.

Let’s take a closer look at some of the security concerns and, most importantly, what you can do to protect yourself.
