When QR Codes (short for "Quick Response" because they can quickly be read by a mobile device) started showing up all over the place, I didn't really understand what they were and why I should use them. I've since learned that they're similar to a bar code except they can store far more data, such as website addresses, business card information, coupons, and app downloads.
Years ago, I downloaded one of the many free QR reader apps. But, whenever I'd be flipping through a magazine or walking by a sign that displayed one of these things, I could never remember which of the (literally) hundreds of apps on my phone could read it much less what the square thingies were called. All of that has changed with iOS11. All you have to do is aim your camera at the code and BAM .... the camera reads it and takes you to wherever the QR code is pointing. It's that simple! And, Android users have the same camera functionality using Google Lens (but only with certain phones).
If you haven't already done so, I urge you to test it out! You may find that it's far handier than you ever thought.
