What to avoid, and how to use the QR code safely
We’ve all seen or used QR codes. They were first popular in the 1990s seen as an upgrade to bar codes. QR (which stands for “Quick Response”) saw a resurgence in popularity during the pandemic when people and businesses went to great lengths to avoid or minimize contact. Unlike a barcode, which holds information horizontally, the QR code stores both vertically and horizontally, meaning it can hold significantly more information.
The QR code is designed for scanning by a camera. Most of us use the camera on a smartphone. QR codes store web links but can also store text and images. The QR reader on the phone deciphers the code, and shows the URL. From there, it’s a simple tap to have your smartphone’s browser open the webpage.
It’s quick. It’s convenient. It enables people to access a website by a point and click. But in this day and age where there is so much worry about hacking and cyber crime, you might be tempted to ask “Is the QR code safe?”
The answer is a qualified “Yes, but…”Use the same precautions with QR codes that you would emails or links that come across your email or browser. There are scammers who will create QR codes for nefarious purposes. You might see a lone QR code on a piece of paper taped to a telephone pole, or on a bulletin board at a bus station, for example. Those are QR codes you should avoid.
Also beware of QR codes in an email from someone you don’t recognize, or in what you think may be a “pfishing” scam. If the email is potentially unsafe, it’s a good bet that the QR code is unsafe also. And don’t’ be lulled into downloading QR scanner apps for your phone. Some may be legitimate but it’s the perfect Trojan Horse for a scammer to plant malware. Use your smartphone camera instead.
“Trust but verify” is a saying that one of our US presidents used in negotiating treaties with other countries. The advice applies equally well here. If you open a link in a QR code, be certain that the URL is safe and comes from a trusted source. Scammers are more clever than ever today and can often include a familiar looking logo which may make the code or website look legitimate when it is not.
