Reading QR codes has become very common in recent years, especially with the rise in smartphone usage. QR codes can be scanned using a smartphone camera to direct you to a website, display text, or perform other actions. But what if you don’t have a smartphone? Is there still a way to read QR codes?
What is a QR code?
QR code stands for “Quick Response” code. It is a type of barcode that can be scanned by a smartphone or QR code reader to provide quick access to information. The black and white boxes represent binary code that contains things like website URLs, phone numbers, emails, text messages and more.
QR codes are able to hold much more information than regular barcodes. They were invented in 1994 by a subsidiary of Toyota to track vehicles during the manufacturing process. Over the years, QR codes have become popular outside of the automotive industry because they provide a quick and easy way to get information by scanning a code.
Can you read a QR code without a smartphone?
Yes, there are a few options for reading QR codes without needing a smartphone.
Use a dedicated QR code scanner
There are dedicated QR code scanner devices that can scan and read QR codes. Many of these devices are affordable, portable handheld scanners. They function similarly to a barcode scanner you might see in a store.
Some QR scanners connect to your smartphone or computer to transfer the information via Bluetooth or cable. Standalone models will display the QR code information directly on a small built-in screen.
Install a QR code scanner app on a tablet
Most tablets like iPads and Android tablets have cameras that are capable of scanning QR codes. By installing a QR reader app on your tablet, you can use its camera to easily scan codes without a smartphone.
There are many free QR scanner apps available for both operating systems. The tablet just needs an active internet connection to redirect you to the QR code link after scanning.
Use your desktop webcam
Your desktop computer’s webcam can also function as a QR code scanner with the right software. There are programs that enable QR scanning capability using your webcam.
Most will provide an overlay display that detects and reads the QR code from your webcam feed. The program automatically opens the QR code link in your web browser.
Install a QR code scanner extension on your browser
Many web browsers offer QR code scanner extensions or add-ons that can read QR codes using your device’s camera. This allows you to scan codes without installing additional software.
For example, Chrome has the QR Code Reader extension that works right within the browser. Firefox has options like QR Code Reader and QR Code Scan.
What devices can scan QR codes?
In addition to the previous methods, here are some other devices capable of scanning and reading QR codes:
- Digital cameras – Many regular digital cameras can read QR codes if you take a photo of the code
- iPads/Tablets – Using the rear camera and a QR reader app
- Smart watches – QR code apps allow scanning from your wrist
- Laptop webcams – With QR scanning software installed
Even some feature phones with cameras can scan QR codes using the pre-installed QR reader app if available. Of course, the most convenient way is using a smartphone, but it’s good to know there are alternatives.
