QR codes are becoming increasingly popular. Here's how to scan a QR code on your Android phone or tablet.

While most people have heard of QR codes, not everyone has used one yet. A QR code (abbreviated from Quick Response Code) is a matrix barcode that contains information about the item to which it is attached. When scanned with the correct application, this code leads the user to additional information or websites related to the product in question. The QR code was developed in Japan and was intended to be used as an efficient way to deliver location-specific data quickly to mobile phones.

What is a QR Code?

A QR Code is made up of rows and columns of small black squares that represent the dark parts of the image, as well as some transparent squares that can be used for special formatting like an encoded text message or website URL. A single QR Code symbol can store data in its square modules; to decode it, use this free app. There’s no need for Internet access—the reader is able to work offline and make sense of the visual patterns it finds in any available light level and from almost any angle.

Why should I use it?

Where can I find them?

QR Codes may not be seen as often as they were in the 1990s, but that doesn’t mean they’re dead. As with anything that is somewhat of a mystery to people, its usage will vary depending on who you talk to – but if someone has one and wants you to download an app, use their WiFi hotspot, or take advantage of some other service, scanning their code is likely the quickest way for them to give you access without having to type in any long strings of text or email addresses with even longer strings of numbers. These are also great if you have received an attachment from someone with no idea what it is – just point your camera at the code and find out!

Are there some privacy concerns?

Just like any other photo you take with your camera, the photo is stored in your Photos app and can be seen by anyone who has access to the device– such as law enforcement personnel if they have a warrant.

How do I protect myself from potential harm when scanning?

Scanning a qr code isn’t hard, but it can be tricky when you’re standing in the wrong place and have dirty hands, in bad lighting, etc. Before you spend time trying to scan a qr code, think about the following:

  • Why am I scanning this?
  • What is my goal in scanning this qr code?
  • Can I complete my goal without scanning the qr code?

When should I avoid using it?

Scanning the wrong kind of code can lead you down the wrong path so make sure you’re scanning the right type of code. Some types include: URLs, which takes you to a web site; Phone numbers, which dials a number from your contact list; email addresses, which will open up an email app with that person already inserted as the recipient; text files (.txt), which opens up a basic editor with that file already loaded and ready for editing.

Be careful not to scan too quickly because this might cause Android OS to misread one type of text for another type and lead you in the wrong direction.
