On our computers and smartphones, sharing a link to a website is as easy as copying the link, pasting it in a message or email, and you’re done. All the receiver needs to do is click on the link and it will load on their browser. Unfortunately, in real life it’s not quite as simple, especially if you have a long or complicated URL.
This is where QR codes come in handy, where they are similar to a barcode where they contain information about something, where upon scanning it, that information will be loaded. It was originally developed back in the 1990s and was used in the Japanese automotive industry, where it contained information about the item that it was paired with.
These days, we’re seeing QR codes everywhere, where they can be used by advertisers and companies to promote their websites, services, sales, and so on. So, the question is, how do you scan a QR code?
How To Scan A QR Code With Your iPhone
If you have an iPhone, scanning a QR code is a pretty simple and straightforward process, and the best part is that you won’t need to deal with third-party QR code scanning apps.
- Launch the Camera app
- Point it at the QR code
- If it is a valid QR code, you will get a notification asking if you want to open the website associated with the QR code
- Tap on the notification and it will load up your browser
While this is an easy way for companies to share their website with their customers in real life without having them type it out, we should mention that there are dangers associated with scanning QR codes in the wild. This is because since QR codes are essentially a container of information, you don’t really know what’s behind it until you click on it.
This means that in theory, people could hide malware behind them and unsuspecting users could be tricked into installing it on their devices. If you’d like to prevent that from happening, you can look into third-party QR code scanning apps. This is because some of these apps do come with added security features that will help prevent these sort of mishaps from happening.
You can also make sure that a QR code is not tampered with by looking closer at it. For example, most QR codes are printed, so if the QR code is a sticker, it could suggest that maybe the original QR code is being covered up and replaced with another QR code. This isn’t to say that all sticker QR codes are malicious or dangerous, but a bit of skepticism and caution could go a long way in protecting yourself.
