In case you didn’t know, barcodes have existed for over 70 years. Because they are so common, we don’t even notice them until we can’t find one on the cereal box we are trying to scan at the self-checkout.
Many years have passed since the first barcode reader, so you might think that your iPhone, with all of its computing power, could quickly scan a barcode. It’s not as easy as you might think, though. You can use the Camera app on your iPhone to read QR codes, but you can’t scan barcodes built-in. Luckily, there is an app for that. There are a lot of them. Here’s how to scan a barcode with an iPhone.

How to Use an App on an iPhone to Scan a Barcode
iPhones don’t have a built-in way to scan barcodes, so you’ll need to get third-party apps. There are a lot of barcode-reading apps out there, but some charge extra to add more features or do more than one scan. Still, some of them are entirely free to use. For this example, we will use the Barcode Scanner – Price Finder app, which you can get for free.

Get the Barcode Scanner – Price Finder app for your iPhone and put it on your phone.
