Barcode Scanner can scan any barcode displayed on the product near MRP. It gets saved automatically and then links the same through search engines to find the description of the product. It uses the camera lens features.
It is to be used by placing the barcode within the allowed area and the application automatically captures the data. I have also downloaded the same on my mobile for checking the information.
This helps in identifying the features of the product and then we can check the same with the actual we have in hand. In my smartphone it is done not in portrait format but on landscape view
