BARCODE & QR READER
You can put your smartphone’s camera to good use for scanning barcodes and QR codes with the help of third-party apps. QR codes are a mosaic of black-and-white squares that offer an efficient link to websites and can even store small information like text, phone numbers, email addresses, calendar events or be used to send SMS messages. Launching the app activates the camera that has an onscreen framing guide. Line up the camera with the QR code and hold the device steadily until the app reads the code. Interestingly, there are apps that let you create your own QR codes. Similarly, using barcode scanner apps, you can scan barcodes as well.
