Quick Response (QR) codes are modern barcodes that look like maze squares, which store small amounts of data like URLs, text or images. You can scan the QR Code and access this information or share contact information, WiFi passwords , or a link to open a website or designated app.
Besides being used for business purposes, QR codes are also used on social media apps. A good example is Snapchat’s Snapcodes, which you and your friends can use to add each other as friends instead of searching for friends manually.
If you received a QR code or your favorite store has offers that are only accessible after scanning a QR code, you can easily access the hidden information behind it using your smartphone.
Whatever your reason for using a QR code, we’ll show you how to scan a QR code on an iPhone and Android device and read or interact with the code’s contents.

Read QR Codes Easily
QR codes are everywhere these days but not all of them are legit. Make sure you only scan QR codes from trusted companies or sources for security reasons.
