Why you should never blindly scan a QR Code
Quick Response (QR) codes are the checkerboard-like squares that are literally everywhere. Initially developed in the 1990s for tracking automotive parts, these high-tech hieroglyphics have evolved into a gateway between the physical and digital worlds. They store information as a series of pixels in a square grid, readable by any smartphone camera. This is why it’s always so frustrating to see people send QR codes in emails and on social media posts; I’m already in the digital space! Just gimme the link already! Anyway, many things are potentially dangerous about blindly scanning a QR Code without first checking where it leads. So, let's "scan" through the ins and outs of QR codes, keeping an eye out for the not-so-funny side of these digital chameleons.
Picture this: you see a QR code sticker on a public poster, promising a great deal or intriguing information. You scan it, only to be redirected to a fraudulent site that looks eerily legitimate. Before you know it, you're inputting sensitive information, from passwords to credit card numbers, right into the hands of cyber tricksters. The malicious force may not have even from the company or service that made the QR code, so many companies are hacked and scraped for user data each day. Scanning a QR code from an unknown source is like accepting a blind date with the internet – you never know what you're going to get. Cybercriminals have caught on, creating malicious QR codes that lead to phishing sites, malware, or worse. Imagine scanning a code for a free cup of coffee and ending up with a free cup of data theft instead. Not exactly the kind of "java" you were hoping for, right?
There have been many instances of QR code fraud that lead to people being scammed. Here some examples:

So, how do you enjoy the benefits of QR codes without falling into the pixel pit? Here are some tips:
Look Before You Leap: If a QR code looks out of place or suspicious (like a sticker on top of an advertisement), maybe just don’t.
Use Trusted Scanners: Some smartphone cameras and QR code scanning apps have built-in security checks to warn you of potentially harmful links.
Peek at the URL: If your scanner shows the URL before opening it, take a moment to ensure it looks legitimate.
Keep Your Software Updated: Regular updates to your smartphone's operating system and security software can provide an extra layer of defense against malware.
QR codes, like any technology, are a double-edged sword. They bring the world to our fingertips, yet can also open the door to digital dangers. By staying alert and following safety practices, we can continue to enjoy the convenience of these quirky squares without falling victim to their darker side. Remember, in the world of QR codes, it's better to be square safe than square sorry!
